Separate runtime TerminalSettings from profile-TerminalSettings (#8602)
<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
The TerminalSettings object we create from profiles no longer gets passed into the control, instead, a child of that object gets passed into the control. Any overrides the control makes to the settings then live in the child. So, when we do a settings reload, we simply update the child's parent and the overrides will remain.

Add support for paste filtering and bracketed paste mode (#9034)
This adds "paste filtering" & "bracketed paste mode" to the Windows
Terminal.

I've moved the paste handling code in `TerminalControl` to
`Microsoft::Console::Util` to be able to easily test it, and the paste
transformer from `TerminalControl` to `TerminalCore`.

Supersedes #7508
References #395 (overall bracketed paste support request)

Tests added. Manually tested.

Add UI for adding, renaming, and deleting a color scheme (#8403)
Introduces the following UI controls to the ColorSchemes page:
- "Add new" button
  - next to dropdown selector
  - adds a new color scheme named ("Color Scheme #" where # is the number of color schemes you have)
- "Rename" Button
  - next to the selector
  - replaces the ComboBox with a TextBox and the accept/cancel buttons appear
- "Delete" button
  - bottom of the page
  - opens flyout, when confirmed, deletes the current color scheme and selects another one

This also adds a Delete button to the Profiles page. The Hide checkbox was moved above the Delete button.

## Detailed Description of the Pull Request / Additional comments

**Color Schemes:**
- Deleting a color scheme selects another one from the list available
- Rename replaces the combobox with a textbox to allow editing
- The Add New button creates a new color scheme named "Color Scheme X" where X is the number of schemes defined
- In-box color schemes cannot be deleted

**Profile:**
- Deleting a profile selects another one from the list available
- the rename button does not exist (yet), because it needs a modification to the NavigationView's Header Template
- The delete button is disabled for in-box profiles (CMD and Windows Powershell) and dynamic profiles

## Validation Steps Performed
**Color Schemes - Add New**
 Creates a new color scheme named "Color Scheme X" (X being the number of color schemes)
 The new color scheme can be renamed/deleted/modified

**Color Schemes - Rename**
 You cannot rename an in-box color scheme
 The rename button has a tooltip
 Clicking the rename button replaces the combobox with a textbox
 Accept --> changes name
 Cancel --> does not change the name
 accepting/cancelling the rename operation updates the combo box appropriately

**Color Schemes - Delete**
 Clicking delete produces a flyout to confirm deletion
 Deleting a color scheme removes it from the list and select the one under it
 Deleting the last color scheme selects the last available color scheme after it's deleted
 In-box color schemes have the delete button disabled, and a disclaimer appears next to it

**Profile- Delete**
 Base layer presents a disclaimer at the top, and hides the delete button
 Dynamic and in-box profiles disable the delete button and show the appropriate disclaimer next to the disabled button
 Clicking delete produces a flyout to confirm deletion
 Regular profiles have a delete button that is styled appropriately
 Clicking the delete profile button opens a content dialog. Confirmation deletes the profile and navigates to the profile indexed under it (deleting the last one redirects to the last one)


## Demo

Fix SA for Visual Studio 16.8 (#8551)
I added `enum class` to one thing and decided that that was quite enough
before disabling the `enum class` warning.

Looks like 16.8 made more map/vector operations noexcept, so we have to
re-annotate to remain compliant.

Correct horizontal coordinates in viewport overflow test (#8456)
When resizing the buffer in the `SetConsoleScreenBufferSize` and
`SetConsoleScreenBufferInfoEx` APIs, we have tests in place to make sure
that the resize doesn't result in the viewport extending past the bottom
or right of the buffer (since that can eventually result in exceptions
being thrown). Unfortunately these tests were using the wrong X
coordinate, so they failed to detect an overflow along the horizontal
axis. This PR corrects that mistake.

PR #8309 was where the overflow detection was initially added.

The original code was using the `Viewport::EndExclusive` method to
determine the extent of the viewport, mistakenly thinking that it
returned the bottom right coordinates (it actually returns the left
coordinate). So I've now added a `BottomRightExclusive` method to the
`Viewport` class, that actually does return the coordinates we need, and
have updated the overflow tests to use that method instead.

## Validation Steps Performed
I've manually confirmed that the test case is issue #8453 is no longer
throwing an exception.

UIA: throw E_FAIL for out-of-bounds text (#8052)
In https://github.com/nvaccess/nvda/issues/11428#issuecomment-715893846,
Andre9642 reported a Conhost crash when switching to/from the alt buffer
a few times with a Braille display connected. Upon further
investigation, @carlos-zamora and I discovered that the FailFast was in
`GetText`: more checks similar to #7677 were needed for this case.

Tested with NVDA using a [Focus](https://www.freedomscientific.com/products/blindness/focus40brailledisplay/) Braille display.

Fully regenerate CodepointWidthDetector from Unicode 13.0 (#8035)
This commit also adds an override UCD and migrates all of the overrides
from GetQuickCharWidth into it.

GetQuickCharWidth
-----------------

The removal of overrides from GQCW reduces the number of comparisons
required for looking up a single character's width from 41 (32
individual ranged comparisons from GQCW + 8+1 from the binary search in
CPWD) to 11 (2 from GQCW, 8+1 from CPWD).

GQCW also incorrectly marked 67 reserved codepoints as `Wide` when they
should have been `Narrow`.

The codepoints whose definitions have changed from `Wide` to `Narrow` are:

```
2E9A 2EF4 2EF5 2EF6 2EF7 2EF8 2EF9 2EFA 2EFB 2EFC 2EFD 2EFE 2EFF 2FD6
2FD7 2FD8 2FD9 2FDA 2FDB 2FDC 2FDD 2FDE 2FDF 2FE0 2FE1 2FE2 2FE3 2FE4
2FE5 2FE6 2FE7 2FE8 2FE9 2FEA 2FEB 2FEC 2FED 2FEE 2FEF 2FFC 2FFD 2FFE
2FFF 31E4 31E5 31E6 31E7 31E8 31E9 31EA 31EB 31EC 31ED 31EE 31EF 321F
A48D A48E A48F FE1A FE1B FE1C FE1D FE1E FE1F FE53 FE67
```

All of them are reserved, but those reserved regions are marked as narrow
in the UCD.

This change also offers us the chance to document exactly why we're
overriding a specific character range. Comments from the override
document will be copied to the generated CPWD table.

New in Unicode 13.0
------------------

Some widths have changed due to previously-reserved characters becoming
_used_ such as U+32FF SQUARE ERA NAME REIWA, the Tangut components
756-768, the entire Khitan Small Script character set, and the Tangut
Ideographs.

A number of the changes in this diff are due to better/worse comment
tracking and the removal of the Emoji/EPres comments. The script once
mistakenly applied comments to packed regions (and it has been updated
to not do so.)

Validation
----------

I build a test application that compared codepoints 0-FFFF for GQCW
against their new registered widths.

Optimize the binary size of the XOrg color table (#7929)
This optimizes the binary size of the xorg color table by replacing the
static lookup table with a table of variable colors (indexed "" (0)
through "4"), calculated greys for gr[ae]y0-100, and a table of the
remaining unsuffixed colors.

78 variable colors ...
  8 bytes each for pointer+size
  5 variants, 4 bytes each for the color data
718 bytes for 0-terminated color names

plus

84 colors ...
  8 bytes each for pointer+size
  4 bytes each for the color data
955 bytes for 8-terminated color names

  2902 = (78 * 8) + (78 * 5 * 4) + 718
+ 1963 = (84 * 8) + (84   *   4) + 955
------
  4865 bytes (approximately)

"I couldn't sleep at night thinking that after years of accusing Windows
being bloated and literally making it even more bloated with my hands.
So here you go. The mediocre yet working solution. This reduces the
binary size to 1051k (1067k before) while keeping the code maintainable
for human beings."

Add support for more OSC color formats (#7578)
* Correct the behaviour of parsing `rgb:R/G/B`. It should be interpreted
  as `RR/GG/BB` instead of `0R/0G/0B`
* Add support for `rgb:RRR/GGG/BBB` and `rgb:RRRR/GGGG/BBBB`. The
  behaviour of 12 bit variants is to repeat the first digit at the end,
  e.g. `rgb:123/456/789` becomes `rgb:1231/4564/7897`.
* Add support for `#` formats. We are following the rules of
  [XParseColor] by interpreting `#RGB` as `R000G000B000`.
* Add support for XOrg app color names, which are supported by xterm, VTE
  and many other terminal emulators.
* Multi-parameter OSC 4 is now supported.
* The chaining of OSC 10-12 is not yet supported. But the parameter
  validation is relaxed by parsing the parameters as multi-params but
  only use the first one, which means `\e]10;rgb:R/G/B;` and
  `\e]10:rgb:R/G/B;invalid` will execute `OSC 10` with the first color
  correctly. This fixes some of the issues mentioned in #942 but not
  all of them.

Fix UIA ScrollIntoView at EndExclusive (#7868)
`ScrollIntoView` is responsible for scrolling the viewport to include
the UTR's start endpoint. The crash was caused by `start` being at the
exclusive end, and attempting to scroll to it. This is now fixed by
clamping the result to the bottom of the buffer.

Most of the work here is to allow a test for this. `ScrollIntoView`
relied on a virtual `ChangeViewport` function. By making that
non-virtual, the `DummyElementProvider` in the tests can now be a
`ScreenInfoUiaProviderBase`. This opens up the possibility of more
UiaTextRange tests in the future too.

Properly handle and test a11y movement at end of buffer (#7792)
The `MovementAtExclusiveEnd` test was improperly authored for the
following reasons:
- it should have used `TEST_METHOD_PROPERTY` to cover all of the
  TextUnits
- TextUnit::Document (arguably one of the most important) was ommitted
  accidentally (`!= TextUnit_Document` was used instead of `<=`)
- The created range was not `EndExclusive`, but rather, the last cell in
  the buffer (`EndInclusive`)

The first half of this PR fixes the test.

The second half of this PR expands the test and fixes any related issues
to make the test pass (i.e. #7771):
- `TEST_METHOD_PROPERTY` was added for it to be degenerate (start/end at
  `EndExclusive`) or not (last cell of buffer)
- `utr->_start` is now also validated after moving backwards

NOTE: `utr->_start` was not validated when moving forwards because
moving forwards should always fail when at/past the last chell in the
buffer.

Keep degenerate UIA text ranges degenerate after movement (#7530)
Conhost expands UIA text ranges when moved. This means that degenerate
ranges become non-degenerate after movement, leading to odd behaviour
from UIA clients. This PR doesn't expand degenerate ranges, but rather
keeps them degenerate by moving `_end` to the newly-changed `_start`.

Tested in the NVDA Python console (cases with `setEndPoint` and
`compareEndPoints` described in #7342). Also ran the logic by
@michaeldcurran.

Closes #7342

Almost definitely addresses nvaccess/nvda#11288 (although I'll need to
test with my Braille display). Also fixes an issue privately reported to
me by @simon818 with copy/paste from review cursor which originally lead
me to believe the issue was with `moveEndPointByRange`.

Always create a new environment block before we spawn a process (#7243)
This commit ensures that we always furnish a new process with the
cleanest, most up-to-date environment variables we can. There is a minor
cost here in that WT will no longer pass environment variables that it
itself inherited to its child processes.

This could be considered a reasonable sacrifice. It will also remove
somebody else's TERM, TERM_PROGRAM and TERM_PROGRAM_VERSION from the
environment, which could be considered a win.

I validated  that GetCurrentProcessToken returns a token we're
_technically able_ to use with this API; it is roughly equivalent to
OpenProcessToken(GetCurrentProcess) in that it returns the current
active _access token_ (which is what CreateEnvironmentBlock wants.)

There's been discussion about doing a 3-way merge between WT's
environment and the new one. This will be complicated and I'd like to
scream test the 0-way merge first ;P

issues it calls out.)

UIA: use full buffer comparison in rects and endpoint setter (#6447)
In UiaTextRange, `_getBufferSize` returns an optimized version of the
size of the buffer to be the origin and the last character in the
buffer. This is to improve performance on search or checking if you are
currently on the last word/line.

When setting the endpoint and drawing the bounding rectangles, we should
be retrieving the true buffer size. This is because it is still possible
to create UiaTextRanges that are outside of this optimized size. The
main source of this is `ExpandToEnclosingUnit()` when the unit is
`Document`. The end _should_ be the last visible character, but it isn't
because that would break our tests.

This is an incomplete solution. #6986 is a follow up to completely test
and implement the solution.

The crash in #6402 was caused by getting the document range (a range of
the full text buffer),  then moving the end by one character. When we
get the document range, we get the optimized size of the buffer (the
position of the last character). Moving by one character is valid
because the buffer still has more to explore. We then crash from
checking if the new position is valid on the **optimized size**, not the
**real size**.

Replace gsl::at with a new til::at(span) for pre-checked bounds (#6925)
The recent changes to use gsl::span everywhere added a few bounds checks
along codepaths where we were already checking bounds. Some of them may
be non-obvious to the optimizer, so we can now use til::at to help them
along.

To accomplish this, I've added a new overload of til::at that takes a
span and directly accesses its backing buffer.

Replace basic_string_view<T> with span<const T> (#6921)
We were using std::basic_string_view as a stand-in for std::span so that
we could change over all at once when C++20 dropped with full span
support. That day's not here yet, but as of 54a7fce3e we're using GSL 3,
whose span is C++20-compliant.

This commit replaces every instance of basic_string_view that was not
referring to an actual string with a span of the appropriate type.

I moved the `const` qualifier into span's `T` because while
`basic_string_view.at()` returns `const T&`, `span.at()` returns `T&`
(without the const). I wanted to maintain the invariant that members of
the span were immutable.

* Mechanical Changes
   * `sv.at(x)` -> `gsl::at(sp, x)`
   * `sv.c{begin,end}` -> `sp.{begin,end}` (span's iterators are const)

I had to replace a `std::basic_string<>` with a `std::vector<>` in
ConImeInfo, and I chose to replace a manual array walk in
ScreenInfoUiaProviderBase with a ranged-for. Please review those
specifically.

This will almost certainly cause a code size regression in Windows
because I'm blowing out all the PGO counts. Whoops.

Replace the color table init code with two const arrays (#6913)
This results in smaller code and faster copying. I chose til::color even
though it results in slightly worse codegen (byteswapping in a tight
loop) than COLORREF (SSE-enlightened block copy) because eventually the
internal representations of the color tables will also be til::color and
_then_ it will become a block copy.

Move to GSL 3.1.0 (#6908)
GSL 3, the next major version of GSL after the one we're using, replaced
their local implementation of `span` with one that more closely mimics
C++20's span. Unfortunately, that is a breaking change for all of GSL's
consumers.

This commit updates our use of span to comply with the new changes in
GSL 3.

Chief among those breaking changes is:

* `span::at` no longer exists; I replaced many instances of `span::at`
  with `gsl::at(x)`
* `span::size_type` has finally given up on `ptrdiff_t` and become
  `size_t` like all other containers

While I was here, I also made the following mechanical replacements:

* In some of our "early standardized" code, we used std::optional's
  `has_value` and `value` back-to-back. Each `value` incurs an
  additional presence test.
  * Change: `x.value().member` -> `x->member` (`optional::operator->`
    skips the presence test)
  * Change: `x.value()` -> `*x` (as above)
* GSL 3 uses `size_t` for `size_type`.
  * Change: `gsl::narrow<size_t>(x.size())` -> `x.size()`
  * Change: `gsl::narrow<ptrdiff_t>(nonSpan.size())` -> `nonSpan.size()`
    during span construction

I also replaced two instances of `x[x.size() - 1]` with `x.back()` and
one instance of a manual array walk (for comparison) with a direct
comparison.

NOTE: Span comparison and `make_span` are not part of the C++20 span
library.

Account for WHEEL_DELTA when dispatching VT mouse wheel events (#6843)
By storing up the accumulated delta in the mouse input handler, we can
enlighten both conhost and terminal about wheel events that are less
than one line in size. Previously, we had a workaround in conhost that
clamped small scroll deltas to a whole line, which made trackpad
scrolling unimaginably fast. Terminal didn't make this mistake, but it
also didn't handle delta accumulation . . . which resulted in the same
behavior.

MouseInput will now wait until it's received WHEEL_DELTA (well-known
constant, value 120) worth of scrolling delta before it dispatches a
single scroll event.

Future considerations may include sending multiple wheel button events
for every *multiple* of WHEEL_DELTA, but that would be a slightly larger
refactoring that I'm not yet ready to undertake.

There's a chance that we should be dividing WHEEL_DELTA by the system's
"number of lines to scroll at once" setting, because on trackpads
conhost now scrolls a little _slow_. I think the only way to determine
whether this is palatable is to just ship it.

Fixes #6184.

Cache the size viewport structure inside TextBuffer (#6841)
Looking up the size of the viewport from the underlying dimensions of
the structures seemed like a good idea at the time (so it would only be
in one place), but it turns out to be more of a perf cost than we
expected. Not necessarily on any one hot path, but if we sort by
functions in WPR, it was the top consumer on the Terminal side. This
instead saves the size as a member of the `TextBuffer` and serves that
out. It only changes when it is constructed or resized traditionally, so
it's easy to update/keep track of. It impacted conhost/conpty to a
lesser degree but was still noticeable.

JsonUtilsNew will be renamed in a subsequent commit that rewrites our
JSON deserializers.

### Implementer's Notes

I went with telescoping exceptions for the key parsing code, because
it's totally possible that you can be five keys deep and encounter a
type error. This lets us encode information about all failures in the
chain instead of just the topmost one.

The original JsonUtilsNew code changed to use `decay` everywhere because
the tests wouldn't compile. We want to treat `GetValue<const guid>` _the
same as_ `GetValue<guid>`, and this lets us do so. `decay` is awesome.

I've been developing this with a shim that redirects `JsonUtils.h` to
`JsonUtilsNew.h`. I am not comfortable deleting the original until we've
moved off of it, and that _will_ be the subject of a followup PR.

## Validation Steps Performed

So many tests.

Tie up some A11y loose threads (#6417)
This pull request moves WindowUiaProvider back into Win32 interactivity
and deletes all mention of it from Windows Terminal. Terminal does not
have a single toplevel window that requires Console-like UIA, as each
Xaml control inside it is in charge of its own destiny.

I've also merged `IUiaWindow` and `IConsoleWindow` back together, as
well as `WindowUiaProviderBase` and `WindowUiaProvider`.

Things look a lot more like they did before we tore them apart.

Add support for win32-input-mode to conhost, ConPTY, Terminal (#6309)
Adds support for `win32-input-mode` to conhost, conpty, and the Windows
Terminal.

* The shared `terminalInput` class supports sending these sequences when
  a VT client application requests this mode.
* ConPTY supports synthesizing `INPUT_RECORD`s from the input sent to it
  from a terminal
* ConPTY requests this mode immediately on startup (if started with a
  new flag, `PSEUDOCONSOLE_WIN32_INPUT_MODE`)
* The Terminal now supports sending this input as well, when conpty asks
  for it.

Also adds a new ConPTY flag `PSEUDOCONSOLE_WIN32_INPUT_MODE` which
requests this functionality from conpty, and the Terminal requests this
by default.

Also adds `experimental.input.forceVT` as a global setting to let a user
opt-out of this behavior, if they don't want it / this ends up breaking
horribly.

Allow the default profile to be specified by name (#5706)
## Summary of the Pull Request

This looks like a big diff, but there's a bunch of existing code that
just got moved around, and there's a cool new Utils template.

The tests all pass, and this passed manual validation. I tried weird
things like "making a profile named `{                            }`"
(w/ enough spaces to look like a guid), and yeah it doesn't let you
specify that one as a name, but _why would you do that?!_

Okay, this pull request abstracts the conversion of a profile name into
an optional profile guid out of the "New Terminal Tab Args" handler and
into a common space for all of CascadiaSettings to use.

It also cleans up the conversion of indices and names into optional
GUIDs and turns _those_ into further helpers.

It also introduces a cool new template for running value_or multiple
times on a chain of optionals. CoalesceOptionals is a "choose first,
with fallback" for N>1 optionals.

On top of all this, I've built support for an "unparsed default GUID":
we load the user's defaultProfile as a string, and as part of settings
validation we unpack that string using the helpers outlined above.

Correct the default 6x6x6 palette entries (#5999)
There is a range of 216 colors in the default 256-color table that is
meant to be initialized with a 6x6x6 color cube, with each color
component iterating over the values `00`, `5F`, `87`, `AF`, `D7`, and
`FF`. A few of the entries incorrectly had the _red_ component has `DF`,
when it should have been `D7`.  This PR corrects those entries. It also
removes a bit of unnecessary whitespace in the first 100 entries.

## Validation Steps Performed

I have a visual test script that renders the full 256-color palette,
using both the indexed color sequence (`SGR 38;5`) and the equivalent
rgb representation (`SGR 38;2`) side by side. Although the difference
was subtle when it was incorrect, I can now see that it has been fixed.

Partially regenerate codepoint widths from Emoji 13.0 (#5934)
This removes all glyphs from the emoji list that do not default to
"emoji presentation" (EPres). It removes all local overrides, but retains
the comments about the emoji we left out that are Microsoft-specific.

This brings us fully in line with the most popular Terminals on OS X,
except that we squash our emoji down to fit in one cell and they let
them hang over the edges and damage other characters. Oh well.

## Detailed Description of the Pull Request / Additional comments

Late Friday evening, I tested my emoji test file on iTerm2. In so doing, I realized
that @j4james and @leonMSFT were right the entire time in #5914: Emoji
that require `U+FE0F` must not be double-width by default.

I finally banged up a powershell script that parses the UCD and emits a codepoint
width table. Once checked in, this will be definitive.

Switch the Cascadia projects to til::color where it's easily possible to do so (#5847)
This pull request moves swaths of Cascadia to use `til::color` for color
interop. There are still some places where we use `COLORREF`, such as in
the ABI boundaries between WinRT components.

I've also added two more til::color helpers - `with_alpha`, which takes
an existing color and sets its alpha component, and a
`Windows::UI::Color` convertor pair.

Future direction might include a `TerminalSettings::Color` type at the
idl boundary so we can finally stop using UInt32s (!) for color.

## Validation Steps Performed
Tested certain fragile areas:
* [x] setting the background with OSC 11
* [x] setting the background when acrylic is in use (which requires
  low-alpha)

CodepointWidthDetector: reclassify U+25FB, U+25FC as Narrow (#5914)
This seems to be in line with the emoji-sequences table in the latest
version of the Unicode standard: those glyphs require U+FE0F to activate
their emoji presentation. Since we don't support composing U+FE0F, we
should not present them as emoji by default.

Fixes #5910.

Yes, I hate this.

Revert some emoji back to narrow width
A couple of codepoints, namely the card suites, male and female signs,
and white and black smiling faces were changed to have a two-column
width as part of #5795 since they were specified as emoji in Unicode's
emoji list v13.0[1]. 

These particular glyphs also show up in some of the most fundamental
code pages, such as CP437[2] and WGL4[3]. We should
not be touching the width of the glyphs in these codepages, as suddenly
changing a long-time-running narrow glyph to use two-columns all of a
sudden will surely break (and has already broken) things.

Make most emojis full-width (#5795)
The table that we refer to in `CodepointWidthDetector.cpp` to determine
whether or not a codepoint should be rendered as Wide vs Narrow was
based off EastAsianWidth[1].  If a codepoint wasn't included in this
table, they're considered Narrow. Many emojis aren't specified in the
EAW list, so this PR supplements our table with emoji codepoints from
emoji-data[2] in order to render most, if not all, emojis as full-width. 

There are certain codepoints I've added to the comments (in case we want
to add them officially to the table in the future) that Microsoft
decided to give an emoji presentation even if it's specified as
Narrow/Ambiguous in the EAW list and are _not_ specified in the Unicode
emoji list. These include all of the Mahjong Tiles block, different
direction pencils (✎✐), different pointing index fingers (☜, ☞) among
others. I have no idea if I've captured all of them, as I don't know of
an easy way to detect which are Microsoft specific emojis.

## Validation Steps Performed
I have looked at so many emojis that I dream emoji.

These screenshots aren't encompassing _all_ emoji but I've tried to grab
a couple from all across the codepoint ranges:

Adjusts High DPI scaling to enable differential rendering (#5345)
## Summary of the Pull Request
- Adjusts scaling practices in `DxEngine` (and related scaling practices in `TerminalControl`) for pixel-perfect row baselines and spacing at High DPI such that differential row-by-row rendering can be applied at High DPI.

## References
- #5185

* [x] I work here.
* [x] Manually tested.
* [x] No doc.
* [x] Am core contributor. Also discussed with some of them already via Teams.

## Detailed Description of the Pull Request / Additional comments

**WAS:**
- We were using implicit DPI scaling on the `ID2D1RenderTarget` and running all of our processing in DIPs (Device-Independent Pixels). That's all well and good for getting things bootstrapped quickly, but it leaves the actual scaling of the draw commands up to the discretion of the rendering target.
- When we don't get to explicitly choose exactly how many pixels tall/wide and our X/Y placement perfectly, the nature of floating point multiplication and division required to do the presentation can cause us to drift off slightly out of our control depending on what the final display resolution actually is.
- Differential drawing cannot work unless we can know the exact integer pixels that need to be copied/moved/preserved/replaced between frames to give to the `IDXGISwapChain1::Present1` method. If things spill into fractional pixels or the sizes of rows/columns vary as they are rounded up and down implicitly, then we cannot do the differential rendering.

**NOW:**
- When deciding on a font, the `DxEngine` will take the scale factor into account and adjust the proposed height of the requested font. Then the remainder of the existing code that adjusts the baseline and integer-ifies each character cell will run naturally from there. That code already works correctly to align the height at normal DPI and scale out the font heights and advances to take an exact integer of pixels.
- `TermControl` has to use the scale now, in some places, and stop scaling in other places. This has to do with how the target's nature used to be implicit and is now explicit. For instance, determining where the cursor click hits must be scaled now. And determining the pixel size of the display canvas must no longer be scaled.
- `DxEngine` will no longer attempt to scale the invalid regions per my attempts in #5185 because the cell size is scaled. So it should work the same as at 96 DPI.
- The block is removed from the `DxEngine` that was causing a full invalidate on every frame at High DPI.
- A TODO was removed from `TermControl` that was invalidating everything when the DPI changed because the underlying renderer will already do that.

UIA: Prevent crash from invalid UTR endpoint comparison (#5399)
## Summary of the Pull Request
This is a quick-and-easy solution to #5309. If the ITextRangeProvider API allows us to take in two UiaTextRanges, we need to verify that they are both valid.

With this PR, we make sure they both fit in the current TextBuffer. If not, we return `E_FAIL`. Though this doesn't prove that both UiaTextRanges are from the same TextBuffer, at the very least we don't crash and in cases where we can't make a valid comparison, we return an HRESULT failure.

## References
#5406 - This should be the proper solution to this problem. Each UiaTextRange needs to be aware of which TextBuffer it came from.

## PR Checklist
* [X] Closes #5309

## Validation Steps Performed
1. generate enough output to cause the terminal to scroll
2. execute `nano` to make us go into the alternate buffer

Fix a deadlock and a bounding rects issue in UIA (#5385)
The scroll locking rework that landed with the DxRenderer's partial
invalidation change introduced a deadlock. UIA locks the buffer for
reading before asking it to scroll (which now requires a write lock.)

Scrolling is probably _okay_ to have a little bit of torn state that
might arise from us unlocking the read lock early before triggering the
write lock down the line.

While investigating this, I also noticed that our bounding rects stopped
being viewport-relative (and were instead buffer-relative.) That
regressed with the switch to `GetTextRects` in #4991

Import fmtlib/fmt@6.2.0, a C++20-style format library (#5336)
We received a request from our localization team to switch from
printf-style format strings (%s, %u) to format strings with positional
argument support. I've been hoping for a long time to take a dependency
on C++20's std::format, but we're just not somewhere we can do that.
Enter fmt. fmt is _exactly_ the library we need.

Minor comparison:

std::wstring_view world = /* ... */;
auto str{ wil::str_printf<std::wstring>(L"hello %.*s",
	   gsl::narrow_cast<size_t>(world.size()),
	   world.data()) };

---

auto str{ fmt::format(L"hello {0}", world) };

If you really want to use the print specifiers:

auto str{ fmt::printf(L"hello %s", world) };

It's got optional compile-time checking for format strings and is
MIT-licensed. Eventually, we should be able to replace fmt:: with std::
and end up pretty much where we left off.
What more could you ask for?

Make CodepointWidthDetector::GetWidth faster (#3727)
This is a subset of #3578 which I think is harmless and the first step towards making things right.
References #3546 #3578 

## Detailed Description of the Pull Request / Additional comments

For more robust Unicode support, `CodepointWidthDetector` should provide concrete width information rather than a simple boolean of `IsWide`. Currently only `IsWide` is widely used and optimized using quick lookup table and fallback cache. This PR moves those optimization into `GetWidth`.

Add more object ID tracing for Accessibility (#5215)
## Summary of the Pull Request

In preparation for getting more accessibility-related issues, I added an ID to the `ScreenInfoUiaProvider` (SIUP) and abstracted the one from `UiaTextRange`. Using this, I noticed that we are creating SIUPs when a new tab/pane is created. This is _good_. This means that we need to somehow notify a UIA Client that out structure has changed, and we need to use the new SIUP because the old one has been removed.

I'll be investigating that more after this PR lands.
