Introduce a `ProfileWriter` abstraction to replace the callback passed to `__llvm_ctx_profile_fetch`. Subsequent changes will add support for flat profile collection (as in, collection of non-contextual profile for those functions not under a contextual root), which require also a change in the profile format. The abstraction makes it easy to add "write flat" - related capabilities without constantly complicating the signature of `__llvm_ctx_profile_fetch`.
