Standardize the color table order (#11602)
## Summary of the Pull Request

In the original implementation, we used two different orderings for the color tables. The WT color table used ANSI order, while the conhost color table used a Windows-specific order. This PR standardizes on the ANSI color order everywhere, so the usage of indexed colors is consistent across both parts of the code base, which will hopefully allow more of the code to be shared one day.

## References

This is another small step towards de-duplicating `AdaptDispatch` and `TerminalDispatch` for issue #3849, and is essentially a followup to the SGR dispatch refactoring in PR #6728.

## Detailed Description of the Pull Request / Additional comments

Conhost still needs to deal with legacy attributes using Windows color order, so those values now need to be transposed to ANSI colors order when creating a `TextAttribute` object. This is done with a simple mapping table, which also handles the translation of the default color entries, so it's actually slightly faster than the original code.

And when converting `TextAttribute` values back to legacy console attributes, we were already using a mapping table to handle the narrowing of 256-color values down to 16 colors, so we just needed to adjust that table to account for the translation from ANSI to Windows, and then could make use of the same table for both 256-color and 16-color values.

There are also a few places in conhost that read from or write to the color tables, and those now need to transpose the index values. I've addressed this by creating separate `SetLegacyColorTableEntry` and `GetLegacyColorTableEntry` methods in the `Settings` class which take care of the mapping, so it's now clearer in which cases the code is dealing with legacy values, and which are ANSI values.

These methods are used in the `SetConsoleScreenBufferInfoEx` and `GetConsoleScreenBufferInfoEx` APIs, as well as a few place where color preferences are handled (the registry, shortcut links, and the properties dialog), none of which are particularly sensitive to performance. However, we also use the legacy table when looking up the default colors for rendering (which happens a lot), so I've refactored that code so the default color calculations now only occur once per frame.

The plus side of all of this is that the VT code doesn't need to do the index translation anymore, so we can finally get rid of all the calls to `XTermToWindowsIndex`, and we no longer need a separate color table initialization method for conhost, so I was able to merge a number of color initialization methods into one. We also no longer need to translate from legacy values to ANSI when generating VT sequences for conpty.

The one exception to that is the 16-color VT renderer, which uses the `TextColor::GetLegacyIndex` method to approximate 16-color equivalents for RGB and 256-color values. Since that method returns a legacy index, it still needs to be translated to ANSI before it can be used in a VT sequence. But this should be no worse than it was before.

One more special case is conhost's secret _Color Selection_ feature. That uses `Ctrl`+Number and `Alt`+Number key sequences to highlight parts of the buffer, and the mapping from number to color is based on the Windows color order. So that mapping now needs to be transposed, but that's also not performance sensitive.

The only thing that I haven't bothered to update is the trace logging code in the `Telemetry` class, which logs the first 16 entries in the color table. Those entries are now going to be in a different order, but I didn't think that would be of great concern to anyone.

## Validation Steps Performed

A lot of unit tests needed to be updated to use ANSI color constants when setting indexed colors, where before they might have been expecting values in Windows order. But this replaced a wild mix of different constants, sometimes having to use bit shifting, as well as values mapped with `XTermToWindowsIndex`, so I think the tests are a whole lot clearer now. Only a few cases have been left with literal numbers where that seemed more appropriate.

In addition to getting the unit tests working, I've also manually tested the behaviour of all the console APIs which I thought could be affected by these changes, and confirmed that they produced the same results in the new code as they did in the original implementation.

This includes:
- `WriteConsoleOutput`
- `ReadConsoleOutput`
- `SetConsoleTextAttribute` with `WriteConsoleOutputCharacter`
- `FillConsoleOutputAttribute` and `FillConsoleOutputCharacter` 
- `ScrollConsoleScreenBuffer`
- `GetConsoleScreenBufferInfo`
- `GetConsoleScreenBufferInfoEx`
- `SetConsoleScreenBufferInfoEx`

I've also manually tested changing colors via the console properties menu, the registry, and shortcut links, including setting default colors and popup colors. And I've tested that the "Quirks Mode" is still working as expected in PowerShell.

In terms of performance, I wrote a little test app that filled a 80x9999 buffer with random color combinations using `WriteConsoleOutput`, which I figured was likely to be the most performance sensitive call, and I think it now actually performs slightly better than the original implementation.

I've also tested similar code - just filling the visible window - with SGR VT sequences of various types, and the performance seems about the same as it was before.

Reduce usage of Json::Value throughout Terminal.Settings.Model (#11184)
This commit reduces the code surface that interacts with raw JSON data,
reducing code complexity and improving maintainability.
Files that needed to be changed drastically were additionally
cleaned up to remove any code cruft that has accrued over time.

In order to facility this the following changes were made:
* Move JSON handling from `CascadiaSettings` into `SettingsLoader`
  This allows us to use STL containers for data model instances.
  For instance profiles are now added to a hashmap for O(1) lookup.
* JSON parsing within `SettingsLoader` doesn't differentiate between user,
  inbox and fragment JSON data, reducing code complexity and size.
  It also centralizes common concerns, like profile deduplication and
  ensuring that all profiles are assigned a GUID.
* Direct JSON modification, like the insertion of dynamic profiles into
  settings.json were removed. This vastly reduces code complexity,
  but unfortunately removes support for comments in JSON on first start.
* `ColorScheme`s cannot be layered. As such its `LayerJson` API was replaced
  with `FromJson`, allowing us to remove JSON-based color scheme validation.
* `Profile`s used to test their wish to layer using `ShouldBeLayered`, which
  was replaced with a GUID-based hashmap lookup on previously parsed profiles.

Further changes were made as improvements upon the previous changes:
* Compact the JSON files embedded binary, saving 28kB
* Prevent double-initialization of the color table in `ColorScheme`
* Making `til::color` getters `constexpr`, allow better optimizations

The result is a reduction of:
* 48kB binary size for the Settings.Model.dll
* 5-10% startup duration
* 26% code for the `CascadiaSettings` class
* 1% overall code in this project

Furthermore this results in the following breaking changes:
* The long deprecated "globals" settings object will not be detected and no
  warning will be created during load.
* The initial creation of a new settings.json will not produce helpful comments.

Both cases are caused by the removal of manual JSON handling and the
move to representing the settings file with model objects instead

Add support for a profile to specify an "unfocused" appearance (#8392)
This pull request adds an appearance configuration object to our
settings model and app lib, allowing the control to be rendered
differently depending on its state, and then uses it to add support for
an "unfocused" appearance that the terminal will use when it's not in
focus.

To accomplish this, we isolated the appearance-related settings from
Profile (into AppearanceConfig) and TerminalSettings (into the
IControlAppearance and ICoreAppearance interfaces). A bunch of work was
done to make inheritance work.

The unfocused appearance inherits from the focused one _for that
profile_. This is important: If you define a
defaults.unfocusedAppearance, it will apply all of defaults' settings to
any leaf profile when a terminal in that profile is out of focus.

Closes #3062
Closes #2316

Bugfix: update color scheme references properly (#9103)
`CascadiaSettings::UpdateColorSchemeReferences` had two bugs in it:
1. we would never check/update the base layer
2. we would explicitly set the color scheme on a profile referencing the
   old name

This PR fixes both of those issues by checking/updating the base layer,
and ensuring that we check if a profile has an explicit reference before
updating it.

Since the affected code is in TSM, I also created an automated local
test.

## Validation Steps Performed
Bug repro steps.
Specifically tested [DHowett's scenario] too.
Test added.

Closes #9094

Introduce TerminalSettingsModel project (#7667)
Introduces a new TerminalSettingsModel (TSM) project. This project is
responsible for (de)serializing and exposing Windows Terminal's settings
as WinRT objects.

## References
#885: TSM epic
#1564: Settings UI is dependent on this for data binding and settings access
#6904: TSM Spec

In the process of ripping out TSM from TerminalApp, a few other changes
were made to make this possible:
1. AppLogic's `ApplicationDisplayName` and `ApplicationVersion` was
   moved to `CascadiaSettings`
   - These are defined as static functions. They also no longer check if
     `AppLogic::Current()` is nullptr.
2. `enum LaunchMode` was moved from TerminalApp to TSM
3. `AzureConnectionType` and `TelnetConnectionType` were moved from the
   profile generators to their respective TerminalConnections
4. CascadiaSettings' `SettingsPath` and `DefaultSettingsPath` are
   exposed as `hstring` instead of `std::filesystem::path`
5. `Command::ExpandCommands()` was exposed via the IDL
   - This required some of the warnings to be saved to an `IVector`
     instead of `std::vector`, among some other small changes.
6. The localization resources had to be split into two halves.
   - Resource file linked in init.cpp. Verified at runtime thanks to the
     StaticResourceLoader.
7. Added constructors to some `ActionArgs`
8. Utils.h/cpp were moved to `cascadia/inc`. `JsonKey()` was moved to
   `JsonUtils`. Both TermApp and TSM need access to Utils.h/cpp.

A large amount of work includes moving to the new namespace
(`TerminalApp` --> `Microsoft::Terminal::Settings::Model`).

Fixing the tests had its own complications. Testing required us to split
up TSM into a DLL and LIB, similar to TermApp. Discussion on creating a
non-local test variant can be found in #7743.

Closes #885
