Right now, GuardObject is in charge of both reading and writing to the guard
byte, and co-ordinating with the InitByte... classes. In order to improve
separation of concerns, create a separate class responsible for managing the
guard byte and use that inside GuardObject.

This is the 3rd of 5 changes to overhaul cxa_guard.
See D108343 <https://reviews.llvm.org/D108343> for what the final result will be and more details on why
cxa_guard is getting overhauled.

Depends on D110088 <https://reviews.llvm.org/D110088>
