The android extension enables the driver to blit from single-sampled
color attachments.
Adding this image usage expressess that functionality and causes anv to
generate the ISL_FORMAT_RAW-formatted clear color during fast-clears.
This fixes an assert failure when anv tries to override the clear color
format used for a blorp_blit() call to ISL_FORMAT_RAW.
There are other ways to handle this, but this solution is consistent
with our handling of multisample images (which may be resolved as well).
