drm/amdgpu: Add EXT_COHERENT memory allocation flags
These flags (for GEM and SVM allocations) allocate
memory that allows for system-scope atomic semantics.
On GFX943 these flags cause caches to be avoided on
non-local memory.
On all other ASICs they are identical in functionality to the
equivalent COHERENT flags.
