  -----------
  clang: Store vendor GPU kinds in OffloadArch instead of re-listing GPUs (#213362)

OffloadArch was a flat enum that hand-duplicated every AMDGPU and NVPTX
target, plus a few edge cases. This was yet another place that needed
updating every time a new target is added, which should now be avoided.
Replace with a tagged union-like scheme.
