iris: Split out an IRIS_DOMAIN_SAMPLER_READ domain from OTHER_READ

Browse Source 
The bulk of IRIS_DOMAIN_OTHER_READ domain usage was the 3D sampler, but
there were also a few oddball cases like command streamer reads, blitter
access, and so on.  The sampler is definitely L3 coherent, but some off
the more esoteric reads may not be, so I'd like to separate them, so
that OTHER_READ can become a non-L3-coherent kitchen-sink domain.

The sampler cases only need TEXTURE_CACHE_INVALIDATE, and can skip the
CONSTANT_CACHE_INVALIDATE we had on IRIS_DOMAIN_OTHER_READ.
