Use a bitfield instead of TextPosition to save bytes in CompactToken
We could use the remaining 25-bits left over from the other bitfields in CompactToken to save 4 bytes in CompactToken.
We have a lot of CompactTokens while parsing a Document, so keeping them small seems important. :)
We'll have to verify with a perf test (telemetry?) to make sure that this is actually a win.
