We'll need this for a few edge cases, like image/sampler view that uses
a format that UBWC does not support with a resource originally created
in a format that UBWC does support.
NOTE we *could* in some cases do an in-place uncompress. But that has
a couple potential sharp edges:
1) the uncompressed buffer could have different layout, ie. a5xx
with meta and pixel data of layers/levels interleaved.
2) if it comes mid-batch, it would force flush, or somehow fixing
up cmdstream for draws already emitted. But with the resource
shadowing approach we can rely on batch re-ordering to avoid
splitting things.. older draws see the older compressed version,
newer draws see the new uncompressed version of the rsc.
