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. Co-authored-by: Rakhi Sharma <atbrakhi@igalia.com>
