## Summary of the Pull Request
This PR adds a global "language" setting, which may be set to any supported BCP 47 tag.
Additionally a ComboBox is added to the settings UI under "Appearance", listing all languages with their localized names.
This PR introduces one new issue: If you change the language while the app is running, the UI will be in a torn state, as not all UI elements refresh automatically if the `PrimaryLanguageOverride` is changed.
## PR Checklist
* [x] Closes#5497
* [x] I work here
* [x] Tests added/passed
* [ ] Documentation updated. If checked, please file a pull request on [our docs repo](https://github.com/MicrosoftDocs/terminal) and link it here: #xxx
* [x] Schema updated
## Validation Steps Performed
* UI language changes when changing the "language" in settings.json before starting WT / while WT is running. ✔️
* "language" field is removed from settings.json if "Use system default" is selected. ✔️
* "language" field is added or updated in settings.json if any other language is selected. ✔️
* Removes qps- languages if debugFeatures is false. ✔️
* Correctly refreshes all UI elements with the new language. ❌
## Summary of the Pull Request
Introduces `til::rle`, a vector-like container which stores elements of
type T in a run length encoded format. This allows efficient compaction
of repeated elements within the vector.
## References
* #8000 - Supports buffer rewrite work. A re-use of `til::rle` will be
useful as a column counter as we pursue NxM storage and presentation.
* #3075 - The new iterators allow skipping forward by multiple units,
which wasn't possible under `TextBuffer-/OutputCellIterator`.
Additionally it also allows a bulk insertions.
* #8787 and #410 - High probability this should be `pmr`-ified
like `bitmap` for things like `chafa` and `cacafire`
which are changing the run length frequently.
## PR Checklist
* [x] Closes#8741
* [x] I work here.
* [x] Tests added.
* [x] Tests passed.
## Validation Steps Performed
* [x] Ran `cacafire` in `OpenConsole.exe` and it looked beautiful
* [x] Ran new suite of `RunLengthEncodingTests.cpp`

## Detailed Description of the Pull Request / Additional comments
I've replaced the `dictionary` directory with `allow` and `reject`. When terminal got check-spelling, I didn't have a way to do `allow`/`reject` (but they were added a while ago). With this release, the bot will complain about items that are in user managed files that wouldn't be valid, this is mostly `-`s in dictionary files, but it also includes numbers `0`..`9` and `_`. If a specific token needs to be accepted but not its sub-elements, the item should be added to `patterns.txt` instead (`D2DERR_SHADER_COMPILE_FAILED` is an example).
With this version, check-spelling defaults to only considering tokens with at least 3 letters. It's possible to tune it back to 2 (or even 1), but in testing, the 2 character tokens have ended up not being worthwhile. (This can be [adjusted](https://github.com/check-spelling/check-spelling/wiki/Configuration#shortest_word) if it turns out that people manage to misspell two character tokens often enough to justify checking them.)
<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
I ran a number of passes of the spell checker in https://github.com/check-spelling/terminal/actions (note: I tend to delete this repository, so this link may be dead at some point, and action run logs expire).
