Use ShortByteString for FastString
There are multiple reasons we want this:
- Fewer allocations: ByteString has 3 fields, ShortByteString just has one.
- ByteString memory is pinned:
- This can cause fragmentation issues (see for example #13110) but also
- makes using FastStrings in compact regions impossible.
