Add settings to warn about large or multiline pastes (#6631)
Before sending calling the `HandleClipboardData` member function on
the `PasteFromClipboardEventArgs` object when we receive a request
from the `TermControl` to send it the clipboard's text content, we
now display a warning to let the user choose whether to continue or
not if the text is larger than 5 KiB or contains the _new line_
character, which can be a security issue if the user is pasting the
text in a shell.

These warnings can be disabled with the `largePasteWarning` and
`multiLinePasteWarning` global settings respectively.

Refactor TerminalDispatch (graphics) to match AdaptDispatch (#6728)
This is essentially a rewrite of the
`TerminalDispatch::SetGraphicsRendition` method, bringing it into closer
alignment with the `AdaptDispatch` implementation, simplifying the
`ITerminalApi` interface, and making the code easier to extend. It adds
support for a number of attributes which weren't previously implemented.

REFERENCES

* This is a mirror of the `AdaptDispatch` refactoring in PR #5758.
* The closer alignment with `AdaptDispatch` is a small step towards
  solving issue #3849.
* The newly supported attributes should help a little with issues #5461
  (italics) and #6205 (strike-through).

DETAILS

I've literally copied and pasted the `SetGraphicsRendition`
implementation from `AdaptDispatch` into `TerminalDispatch`, with only
few minor changes:

* The `SetTextAttribute` and `GetTextAttribute` calls are slightly
  different in the `TerminalDispatch` version, since they don't return a
  pointless `success` value, and in the case of the getter, the
  `TextAttribute` is returned directly instead of by reference.
  Ultimately I'd like to move the `AdaptDispatch` code towards that way
  of doing things too, but I'd like to deal with that later as part of a
  wider refactoring of the `ConGetSet` interface.
* The `SetIndexedForeground256` and `SetIndexedBackground256` calls
  required the color indices to be remapped in the `AdaptDispatch`
  implementation, because the conhost color table is in a different
  order to the XTerm standard. `TerminalDispatch` doesn't have that
  problem, so doesn't require the mapping.
* The index color constants used in the 16-color `SetIndexedForeground`
  and `SetIndexedBackground` calls are also slightly different for the
  same reason.

VALIDATION

I cherry-picked this code on top of the #6506 and #6698 PRs, since
that's only way to really get the different color formats passed-through
to the terminal. I then ran a bunch of manual tests with various color
coverage scripts that I have, and confirmed that all the different color
formats were being rendered as expected.

Closes #6725

Improve the propagation of color attributes over ConPTY (#6506)
This PR reimplements the VT rendering engines to do a better job of
preserving the original color types when propagating attributes over
ConPTY. For the 16-color renderers it provides better support for
default colors and improves the efficiency of the color narrowing
conversions. It also fixes problems with the ordering of character
renditions that could result in attributes being dropped.

Originally the base renderer would calculate the RGB color values and
legacy/extended attributes up front, passing that data on to the active
engine's `UpdateDrawingBrushes` method. With this new implementation,
the renderer now just passes through the original `TextAttribute` along
with an `IRenderData` interface, and leaves it to the engines to extract
the information they need.

The GDI and DirectX engines now have to lookup the RGB colors themselves
(via simple `IRenderData` calls), but have no need for the other
attributes. The VT engines extract the information that they need from
the `TextAttribute`, instead of having to reverse engineer it from
`COLORREF`s.

The process for the 256-color Xterm engine starts with a check for
default colors. If both foreground and background are default, it
outputs a SGR 0 reset, and clears the `_lastTextAttribute` completely to
make sure any reset state is reapplied. With that out the way, the
foreground and background are updated (if changed) in one of 4 ways.
They can either be a default value (SGR 39 and 49), a 16-color index
(using ANSI or AIX sequences), a 256-color index, or a 24-bit RGB value
(both using SGR 38 and 48 sequences).

Then once the colors are accounted for, there is a separate step that
handles the character rendition attributes (bold, italics, underline,
etc.) This step must come _after_ the color sequences, in case a SGR
reset is required, which would otherwise have cleared any character
rendition attributes if it came last (which is what happened in the
original implementation).

The process for the 16-color engines is a little different. The target
client in this case (Windows telnet) is incapable of setting default
colors individually, so we need to output an SGR 0 reset if _either_
color has changed to default. With that out the way, we use the
`TextColor::GetLegacyIndex` method to obtain an approximate 16-color
index for each color, and apply the bold attribute by brightening the
foreground index (setting bit 8) if the color type permits that.

However, since Windows telnet only supports the 8 basic ANSI colors, the
best we can do for bright colors is to output an SGR 1 attribute to get
a bright foreground. There is nothing we can do about a bright
background, so after that we just have to drop the high bit from the
colors. If the resulting index values have changed from what they were
before, we then output ANSI 8-color SGR sequences to update them.

As with the 256-color engine, there is also a final step to handle the
character rendition attributes. But in this case, the only supported
attributes are underline and reversed video.

Since the VT engines no longer depend on the active color table and
default color values, there was quite a lot of code that could now be
removed. This included the `IDefaultColorProvider` interface and
implementations, the `Find(Nearest)TableIndex` functions, and also the
associated HLS conversion and difference calculations.

VALIDATION

Other than simple API parameter changes, the majority of updates
required in the unit tests were to correct assumptions about the way the
colors should be rendered, which were the source of the narrowing bugs
this PR was trying to fix. Like passing white on black to the
`UpdateDrawingBrushes` API, and expecting it to output the default `SGR
0` sequence, or passing an RGB color and expecting an indexed SGR
sequence.

In addition to that, I've added some VT renderer tests to make sure the
rendition attributes (bold, underline, etc) are correctly retained when
a default color update causes an `SGR 0` sequence to be generated (the
source of bug #3076). And I've extended the VT renderer color tests
(both 256-color and 16-color) to make sure we're covering all of the
different color types (default, RGB, and both forms of indexed colors).

I've also tried to manually verify that all of the test cases in the
linked bug reports (and their associated duplicates) are now fixed when
this PR is applied.

Closes #2661
Closes #3076
Closes #3717
Closes #5384
Closes #5864

This is only a partial fix for #293, but I suspect the remaining cases
are unfixable.

Improve conpty rendering of default colors in legacy apps (#6698)
Essentially what this does is map the default legacy foreground and
background attributes (typically white on black) to the `IsDefault`
color type in the `TextColor` class. As a result, we can now initialize
the buffer for "legacy" shells (like PowerShell and cmd.exe) with
default colors, instead of white on black. This fixes the startup
rendering in conpty clients, which expect an initial default background
color. It also makes these colors update appropriately when the default
palette values change.

One complication in getting this to work, is that the console permits
users to change which color indices are designated as defaults, so we
can't assume they'll always be white on black. This means that the
legacy-to-`TextAttribute` conversion will need access to those default
values.

Unfortunately the defaults are stored in the conhost `Settings` class
(the `_wFillAttribute` field), which isn't easily accessible to all the
code that needs to construct a `TextAttribute` from a legacy value. The
`OutputCellIterator` is particularly problematic, because some iterator
types need to generate a new `TextAttribute` on every iteration.

So after trying a couple of different approaches, I decided that the
least worst option would be to add a pair of static properties for the
legacy defaults in the `TextAttribute` class itself, then refresh those
values from the `Settings` class whenever the defaults changed (this
only happens on startup, or when the conhost _Properties_ dialog is
edited).

And once the `TextAttribute` class had access to those defaults, it was
fairly easy to adapt the constructor to handle the conversion of default
values to the `IsDefault` color type. I could also then simplify the
`TextAttribute::GetLegacyAttributes` method which does the reverse
mapping, and which previously required the default values to be passed
in as a parameter 

VALIDATION

I had to make one small change to the `TestRoundtripExhaustive` unit
test which assumed that all legacy attributes would convert to legacy
color types, which is no longer the case, but otherwise all the existing
tests passed as is. I added a new unit test verifying that the default
legacy attributes correctly mapped to default color types, and the
default color types were mapped back to the correct legacy attributes.

I've manually confirmed that this fixed the issue raised in #5952,
namely that the conhost screen is cleared with the correct default
colors, and also that it is correctly refreshed when changing the
palette from the properties dialog. And I've combined this PR with
#6506, and confirmed that the PowerShell and the cmd shell renderings in
Windows Terminal are at least improved, if not always perfect.

This is a prerequisite for PR #6506

Restore simple text runs, correct for crashes (#6695)
Restores the simple text run analysis and skipping of most of the
shaping/layout steps. Corrects one of the fast-path steps to ensure that
offsets and clusters are assigned.

## References
- Bug #6488 
- Bug #6664
- Simple run PR #6206 
- Simple run revert PR #6665
- Recycle glyph runs PR #6483

The "correction" functions, by which box drawing analysis is one of
them, is dependent on the steps coming before it properly assigning the
four main vectors of the text layout glyphs: indices, advances, offsets,
and clusters. When the fast path is identified by the code from #6206,
only two of those are fully updated: indices and advances. The offsets
doesn't tend to cause a problem because offsets are rarely used so
they're pretty much always 0 already (but this PR enforces that they're
zero for the simple/fast path.) The clusters, however, were not mapped
for the fast path. This showed itself in one of two ways:
1. Before the recycled runs PR #6483, the cluster map had a 0 in every
   field for the stock initialized vector.
2. After the recycled runs PR #6483, the cluster map had the previous
   run's mapping in it.

This meant that when we reached the steps where glyph runs were
potentially split during the correction phase for box drawing
characters, unexpected values were present to map the glyph indices to
clusters and were corrected, adjusted, or split in an unexpected
fashion. 

For instance, the index out of range bug could appear when the default 0
values appended to the end of the clusters vector were decremented down
to a negative value during the run splitter as the true DWrite cluster
mapper doesn't generate that sort of pattern in the slow path case
without also breaking the run itself.

The resolution here is therefore to ensure that all of the fields
related to glyph layout are populated even in the fast path. This
doesn't affect the slow path because that one always populated all
fields by asking DWrite to do it. The fast path just skips a bunch of
DWrite steps because it can implicitly identify patterns and save a
bunch of time.

I've also identified a few vectors that weren't cleared on reset/reuse
of the layout. I'm clearing those now so the `.resize()` operations
performed on them to get to the correct lengths will fill them with
fresh and empty values instead of hanging on to ones that may have been
from the previous. This should be OK memory perf wise because the act of
`.clear()` on a vector shouldn't free anything, just mark it invalid.
And doing `.resize()` from an empty one should just default construct
them into already allocated space (which ought to be super quick).

Add support for the Command Palette (#6635)
## Summary of the Pull Request

![command-palette-001](https://user-images.githubusercontent.com/18356694/85313480-b6dbef00-b47d-11ea-8a8f-a802d26c2f9b.gif)


This adds a first iteration on the command palette. Notable missing features are:
* Commandline mode: This will be a follow-up PR, following the merge of #6537
* nested and iterable commands: These will additionally be a follow-up PR.

This is also additionally based off the addenda in #6532. 

This does not bind a key for the palette by default. That will be done when the above follow-ups are completed.

## References
* #2046 - The original command palette thread
* #5400 - This is the megathread for all command palette issues, which is tracking a bunch of additional follow up work 
* #5674 and #6532 - specs

## PR Checklist
* [x] Closes #2046
  - incidentally also closes #6645
* [x] I work here
* [x] Tests added/passed
* [ ] Requires documentation to be updated - delaying this until it's more polished.


## Detailed Description of the Pull Request / Additional comments

* There's a lot of code for autogenerating command names. That's all in `ActionArgs.cpp`, because each case is so _not_ boilerplate, unlike the rest of the code in `ActionArgs.h`.

Hardcode the paths to Windows PowerShell and CMD (#6684)
Occasionally, we get users with corrupt PATH environment variables: they
can't lauch PowerShell, because for some reason it's dropped off their
PATH. We also get users who have stray applications named
`powershell.exe` just lying around in random system directories.

We can combat both of these issues by simply hardcoding where we expect
PowerShell and CMD to live. %SystemRoot% was chosen over %WINDIR%
because apparently (according to Stack Overflow), SystemPath is
read-only and WINDIR isn't.

Implement Shift+MultiClick Selection Expansion (#6322)
This pull request implements shift+double/triple click. Proper behavior
(as described in #4557) is to only expand one selection point, not both.

Adding the `bool targetStart` was a bit weird. I decided on this being
the cleanest approach though because I still want `PivotSelection` to be
its own helper function. Otherwise, the concept of "pivoting" gets kinda
messy.

## Validation Steps Performed

Spec for unified keybindings and commands, and synthesized action names (#6532)
## Summary of the Pull Request

This is another iteration on the Command Palette spec, from #5674. These were some ideas that were tossed around by @DHowett, @cinnamon-msft and myself, formalized here. I proposed this as an addendum to the original spec, since I think the first made sense atomically, and this only makes sense as a set of changes to the original. I didn't want to go hacking up the original doc to add this set of changes. 

**There are two proposals in this spec - they should be viewed as two atomic units. They can be accepted or rejected independently. I'm suggesting we approve both. They work _together_. I'm realizing now that this is worded confusingly, and it's on me to fix that.**

## Detailed Description of the Pull Request / Additional comments

I added a handler for the `DoubleTapped` event on the tab view item
when we are constructing it for the tab (in `Tab::_MakeTabViewItem`).

The code for that handler was copied the "rename tab menu item" click
handler.

I did not extract the code into a member function because it is very
short (only 2 lines of code) and only used twice so it is not worth
it IMO.

Recycle assorted rendering components to accelerate drawing (#6483)
This saves an awful lot of construction/destruction and memory
allocation, especially with text that changes a lot (see: cacafire).

Three things:
1. Recycling the text layouts. This holds onto the `CustomTextLayout` so
   all the things that don't change related to drawing targets and
   whatnot aren't freed and recreated every frame.
2. Reordering the runs in place. This saves a vector
   allocation/copy/delete every time OrderRuns is called. They can be
   rearranged in place.
3. Only clip once per row. This reduces the clip push/pop to only one
   time per row. Since we're always redrawing an entire row at a time,
   this saves a lot of alloc/free of the clip frame, dramatically
   reduces queued commands, and makes less work on the flush since
   clipping requires staging the drawing and then bringing it back to
   the main surface.

Use D2DDeviceContext and friends over D2DRenderTarget (#6527)
I was told that the DeviceContext version supercedes the RenderTarget
one. This moves us to it so we can gain access to a higher level of
control over the various pieces in our pipeline as we continue to evolve
the renderer.

The underlying motivation here is to potentially use a
`ID2D1CommandList` to batch our commands and run them all later outside
the lock. That can only really be done with this more granular level of
control over the pipeline. So this moves to that in a single step that
is easily findable in history should we have problems

I discussed this with @NiklasBorson of the Direct2D/DirectWrite team as
well as with @DHowett before doing it.

## Validation
- [x] Checked docs to make sure that these work on Windows 7 with
  Platform Update
- [x] Manual smoke test real quick
- [ ] Try running on Win7 + Platform Update after change
- [x] Probably do more than just a smoke test manually or otherwise

Enable hot reload of renderer settings that aren't already hot reload capable (#6551)
## Summary of the Pull Request

## PR Checklist
* [x] Closes #3927
* [x] I work here.
* [x] Tested manually.
* [x] Requires documentation to be updated: (generate doc bug here)
* [x] Am core contributor.

## Detailed Description of the Pull Request / Additional comments
- I found four settings that weren't hot reloadable with the 3927 comment above them:
1. Experimental retro terminal effect
2. Experimental software rendering
3. Experimental full repaint rendering
4. Antialiasing settings for text

I made them all hot reloadable by telling the `TermControl` to propagate them on settings change to the `DxEngine`.
Then I set up the `DxEngine` inside the setters to only set them if they changed. And if they do change, to trigger a full repaint and/or a complete drop and recreate of the entire DX device chain (as would happen if it were lost for another reason like a user-mode graphics failure, disconnected display, etc.)
I made the boolean an atomic because the settings can be coming in off of another thread (the XAML eventing one) and the renderer is picking the status up on its thread at the top of the BeginPaint frame.

## Validation Steps Performed
- [x] Opened it up and toggled all the settings while staring at PowerShell
- [x] Opened it up and toggled all the settings while staring at something intensive like a `cacafire` fire

Fixed #6377: TerminalCore::_altGrAliasing is undefined by default (#6571)
## Summary of the Pull Request

Fixes #6377. `TerminalCore` does not initialize `_altGrAliasing`. The impact is minimized in WT because it defaults to `true` in higher layers. It's not initialized when WPF is driving.

Introduce JsonUtilsNew as documented in #5875 (#6355)
Read the [JsonUtils Spec] for more details.

This pull request introduces the next version of JsonUtils. It is in a
separate file for ease of review and testing.

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.

Reintroduce the check for VT_INPUT_MODE in AdaptDispatch (#6485)
This commit reverts the removal of the "SSH hack" in #5383. It was
originally added as a solution to #4911, when we realized that SSH would
request the SS3 cursor key encoding but we weren't equipped to handle
it.

A number of folks have filed issues that, in summary, say "when I use
SSH, I can't select/copy/paste text". It turns out that SSH will _also_
pass through requests for mouse input. Terminal dutifully responds to
those requests, of course, by disabling mouse selection/copy/paste. SSH
is **NOT** actually in VT_INPUT_MODE, so it will never receive the mouse
messages.

It's important to note that even with #376 fixed, we are still required
to keep this check. With the closure of #376, we'll be able to convert
VT mouse input back into Win32 mouse input for Win32 applications . . .
but SSH also doesn't know how to handle Win32 mouse input.

Fixes #6476.
Fixes #6196.
Fixes #5704.
Fixes #5608.

Throttle scrollbar updates in TermControl to ~one per 8ms (#4608)
In addition to the below (original) description, this commit introduces
a ThrottledFunc template that can throttle _any_ function. It applies
that type to muffle updates to the scrollbar.

---

Redo #3531 but without the bug that it caused (#3622) which is why it
was reverted.

I'm sorry if I explain this badly. If you don't understand a part, make
sure to let me know and I will explain it better.

### Explanation

How it worked before: `Terminal` signals that viewport changed ->
`TermControl::_TerminalScrollPositionChanged` gets called on the
terminal thread -> it dispatches work for later to be ran the UI thread
to updates the scrollbar's values

Why it's bad:
* If we have many viewport changes, it will create a long stack of
  operations to run. Instead, we should just update the scroll bar with
  the most recent information that we know.
* Imagine if the rate that the work gets pushed on the UI thread is
  greater than the rate that it can handle: it might freeze?
* No need to be real time, we can wait just a little bit (8ms) to
  accumulate viewport changes before we actually change the scroll bar's
  value because it appears to be expensive (see perf below).

Now: `Terminal` signals that viewport changed ->
`TermControl::_TerminalScrollPositionChanged` gets called on the
terminal thread -> it tells the `ScrollBarUpdater` about a new update ->
the `ScrollBarUpdater` only runs one job (I don't know if that's the
right term) on the UI thread at a time. If a job is already running but
hasn't updated the scroll bar yet, it changes the setting in the already
existing job to update the scroll bar with the new values. A job "waits"
some time before doing the update to throttle updates because we don't
need real time scroll bar updates. -> eventually, it updates the scroll
bar If the user scrolls when a scroll bar update is pending, we keep the
scroll bar's Maximum and Minimum but let the user choose its new Value
with the `CancelPendingValueChange` method.

### Note

Also I changed a little bit the code from the Terminal to notify the
TermControl less often when possible.

I tried to scroll with the scroll bar, with the mouse wheel. I tried to
scroll while content is being outputted.

I tried to reproduce the crash from #2248 without success (good).

Pass <Alt> to the application (#6461)
For mysterious reasons lost to the sands of time, XAML will _never_ pass
us a VK_MENU event. This is something that'll probably get fixed in
WinUI 3, but considering we're stuck on system XAML for the time being,
the only way to work around this bug is to pass the event through
manually. This change generalizes the F7 handler into a "direct key
event" handler that uses the same focus and tunneling method to send
different key events, and then uses it to send VK_MENU.

## Validation Steps Performed

Opened the debug tap, verified that I was seeing alt key ups.
Also used some alt keybindings to make sure I didn't break them.

This PR aims to move the command palette spec out of the draft state and into a finalized state for inclusion in the 2.0 version of the Windows Terminal. 

Notably, I've added sections regarding the ability to run `wt` commandlines using the Command Palette UI, something we hadn't considered in the original draft, because `wt` commandlines didn't land for like _4 months_ after this first draft.

Fix 3 different bugs in the WPF control (#6464)
* [wpf] WM_KEYUP crashes on x64 #6444
  - Turns out that doing the `(uint)lParam` cast worked fine for the
    keydowns, because the value of lParam usually didn't have super
    high-order bits set. That's not the case for keyups, where the 30th
    bit is _always_ set. This is fixed by explicitly getting the byte
    with the scancode in it.
* [wpf] WM_KEYUP generates wrong value in Win32 input mode #6445
  - This was fixed by basically the same thing as the above.
* [wpf] WPF control crashes on startup trying to render cursor #6446
  - This was a regression from #6337. I forgot to initialize the brush
    used to paint the cursor, because the UWP version always uses color
    (but the WPF one relies on the text foreground color).
* Also adds a minor change to the WPF test app, so that the user can
  actually exit `win32-input-mode`.

* #6337 regressed #6446 
* #6309 regressed the other two.
