Fixes MSFT:34673647, at least I'm pretty sure. That's only ever hit a few
times externally, and internally it's hitting a lot on 1.9.1942 builds, which
doesn't really make any sense.
Window sends an event that requests exit from fullscreen then SC_RESTORE messages is sent and it is in fullscreen mode.
Closes#10607
## Validation Steps Performed
Border and tabbar now appear after exiting fullscreen via "win+arrow down".

Implements `_MakePane` in `TerminalPage`, which creates a pane that then can be used to pass into another pane to split or to create a new tab with. Places where we split pane or create a new tab now use `_MakePane`.

## 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.
#11404 changed `_OpenSettingsUI` to `OpenSettingsUI` in `TerminalPage`, but there is still one leftover reference to `_OpenSettingsUI`. This commit fixes that.

## Validation Steps Performed
Introduces X-macros to reduce the number of places we need to write essentially the same line of code but for a different setting (declaring it in the header file, in `Copy`, `LayerJson`, `ToJson`, etc).
## Summary of the Pull Request
There is a non-zero subset of applications that randomly output _Locking Shift_ escape sequences which will invoke a character set from G2 or G3 into the left half of the code table. If those G-sets are mapped to Latin1, that can result in the terminal producing output that appears to be broken. This PR now defaults all G-sets to ASCII, to prevent an unintentional _Locking Shift_ from having any effect.

## Detailed Description of the Pull Request / Additional comments
Most other modern terminals also default to ASCII in all G-sets, so this shouldn't break any modern applications. Legacy 8-bit applications may still expect the G2 and G3 sets mapped to Latin1, but they would also need to have the ISO-2022 encoding enabled, so we can keep them happy by setting G2 and G3 correctly when the ISO-2022 encoding is requested.
## Validation Steps Performed
I've manually confirmed that `echo -e "\en"` and `echo -e "\eo"` no longer have any visible effect on the output (at least without first invoking another character set into G2 or G3). I've also confirmed that they do still work as expected (i.e. selecting Latin1) after enabling the ISO-2022 encoding.
## Summary of the Pull Request
When we are on a settings UI tab, `_GetActiveControl` returns a `nullptr`, make sure not to try and focus it in that case
