freedreno: Use fast variants of {BC4/BC5}_SNORM formats

Browse source 
Hardware has two types of BC4 and BC5: fast and not.
The exact perf difference is not tested, but these distinct formats
could be seen in the public docs:
Qualcomm Adreno GPU > Spec Sheet -> Texture format
https://docs.qualcomm.com/bundle/publicresource/topics/80-78185-2/spec_sheets.html?product=1601111740035277#panel-0-0-1

Found when scanning prop driver's cmdstream seeing unknown format.

Passes:
dEQP-VK.*bc4*
dEQP-VK.*bc5*
