5506a9af - clang/AMDGPU: Mark more capability target features read-only (#214954)

clang/AMDGPU: Mark more capability target features read-only (#214954) Really all amdgpu subtarget features should be read-only, except for a handful of legitimately configurable modes which should be moved out of subtarget features. Add a few special cases here which will help unblock progressing towards using the new generated feature bitset.
