Don't fallback to global capability when skipping client transform

* The display internally already fallsback to global capabilities if the
  display capabilities aren't supported
* If HWC doesn't know about the display, then we need to default to the
  Output behavior, which today always asks the GPU to skip the client
  transform. We do this because today, the per-display color transform
  is actually a *global* transform, but we need to exclude the transform
  for things like screen recording or projected android auto.
