LTO does not set the -import-instr-limit flag when building for
darwin, don't test it on darwin host modules.

afdo.addDep would never add a depencency on a profile for a host
module, but afdoDepsMutator would still propagate AfdoRDeps to
dependencies, afdoMutator would still create afdo variants, and
afdo.flags would still add the -funique-internal-linkage-names
flag. Exit early from all of these functions, since the afdo
variations will never be useful.

Add more coverage to the afdo tests for the arm32 variant of a module
that only has an arm64 profile, for the -funique-internal-linkage-names
flag, and for the interaction between LTO linker flags and AFDO.

Convert afdoDepsMutator and afdoMutator to a TransitionMutator as a
step towards variants-on-demand.

We used to enable unique names only when a profile is available.
But A profile generated for a binary without unique names doesn't
work well when building a binary with unique names. To avoid a
chicken-and-egg problem, this CL enables the flag when afdo=true,
whether a profile exists or not.

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.
