0ccc232691 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.
