radeonsi: expand the compressed color and depth texture masks to 64 bits

This is in preparation of raising the number of exposed sampler views to 32
bits, which will raise the total number of sampler views to 33 for the
polygon stipple texture. That texture should never be compressed (and it's
certainly not a depth texture), but this approach seems cleaner to me than
special-casing the last slot in all affected code paths.
