layout: Add initial support for text-transform (#31396)

This adds basic support for `text-transform` in a way that is more
complete than legacy layout. There are still many missing elements of
proper `text-transform` support such as:

1. Support for `full-width` and `full-size-kana`
2. Support for grapheme based uppercasing, lowercasing, and
   capitalization. These are all done per-code point right now.
3. Support for the language-specific `SpecialCasing.txt` cases for case
   mapping such as the ones for Irish and Turkish.
