anv: Put image params in the descriptor set buffer on gen8 and earlier

Browse Source 
This is really where they belong; not push constants.  The one downside
here is that we can't push them anymore for compute shaders.  However,
that's a general problem and we should figure out how to push descriptor
sets for compute shaders.  This lets us bump MAX_IMAGES to 64 on BDW and
earlier platforms because we no longer have to worry about push constant
overhead limits.
