Elias Naur 039cfcf0de piet-gpu/shader: treat memoryBarrierBuffer as a control barrier ...

memoryBarrierBuffer is mapped to the threadgroup_barrier function in
Metal, which is a control barrier that must be executed by all threads
(or none). This change establishes that property for the two memory
barriers we have.

While here, remove ENABLE_IMAGE_INDICES completely; it was disabled in
an earlier change.
