Implement fdo_profile module type
Introducing fdo_profile module type to reimplement the afdo support in cc moduels. This change allows the feature to be compatible with Bazel migration.
How it works:
PreDepsMutators:
* BeginMutator: If non-static cc modules sets afdo prop, search and add corresponding fdo_profile module as a dep with fdoProfileTag
* fdoProfileMutator:
* If in fdo_profile module, set FdoProfileProvider with full path to profile
* If in cc module, read FdoProfileProvider from dep with fdoProfileTag and set FdoProfileInfo.Path to FdoProfilePath field
PostDepsMutators:
* afdoDepsMutator: If a module has FdoProfilePath set, walk to its static deps and set itself to the deps' AfdoRdeps
* afdoMutator: If a static dep has AfdoRDeps set, create afdo variant.
