Port font handling to fontdock and ttf-parser 🛳

- Use fontdock for indexing fonts and querying
- Typst binary now automatically indexes and uses system fonts in addition to a fixed font folder!
- Removes subsetting support for now (was half-finished anyways, plan is to use harfbuzz for subsetting in the future)
- Adds font width configuration support
