blorp: Use R8G8_UINT for YCRCB_* formats with CCS

BLORP uses the get_ccs_compatible_copy_format() based on whether or not
ISL claims the format supports CCS_E, not whether or not CCS_E is used
on the image.  This is probably a good thing as it improves consistency.
However, it means that we need CCS-compatible formats for YCRCB_*
formats even if we never use them with CCS_E enabled.  In practice,
these do actually seem to work according to the Vulkan CTS but coverage
is likely far less than perfect.
