Introduce til::rle - a run length encoded vector (#10099)
## 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`

ROW: clean up in preparation to hide CharRow & AttrRow (#8446)
Moving things out of CharRow into ROW helps us hide it as an implementation detail.
This is part one of many.

### CharRow: Hide ClearCell, use ROW::ClearColumn

### CharRow: Hide GetText, use ROW::GetText

### CharRowBaseTests: remove dead file (never used!)

### CharRow: Move DoubleBytePadded into ROW

### CharRow: Move WrapForced into ROW

### Char/AttrRow: Hide Reset, use ROW::Reset

### Remove RowCellIterator (dead code)

RCI was unused; it was replaced by TextBufferCellIterator shortly after its creation

### Move AttrRowTests to ut_textbuffer from ut_host

It had no reliance on the host.

Prevent cleanup of object given to handle that failed access check (#3414)
* Ensure rights check and increments pass before assigning an object to a handle (since deallocation of handles will automatically attempt to cleanup).
