anv: Fix get_image_format_properties() - YCbCr

Teach it to calculate the format features for YCbCr.

The goal (which is completed in this patch) is to incrementally fix
get_image_format_properties() to return a correct result.  Previously,
it returned incorrect VkFormatFeatureFlags which the caller needed clean
up.
