[CallSite removal][TargetLibraryInfo] Replace ImmutableCallSite with CallBase in one of the getLibFunc signatures.

[craig.topper]

Remove include of CallSite.h from TargetLibraryInfo.h. Fix transitive include issues.

[craig.topper]

Rebase after removing CallSite from files that transitively included CallSite.h from this file.
