Olivia Lee 8e4c6990a1 panvk: implement non uniform indexing except for input attachments 
We need to lower everything on bifrost, and everything except nonuniform
texture offsets on valhall. With texture offsets, the hardware supports
nonuniform offsets passed in a staging register, but does not support
passing nonuniform offsets as src1 in the narrow layout. We need to make
sure we check for this if we implement narrow offsetms later.

Input attachments are skipped in this commit because they need
additional changes.
