anv: Fall back to HiZ when disabling CCS on HiZ+CCS

Browse Source 
When an image configured for HIZ_CCS/HIZ_CCS_WT is bound to a BO lacking
implicit CCS, we disable any compression it may have had. Such images
are still compatible with ISL_AUX_USAGE_HIZ however. Fall back to that
aux usage to retain the performance benefit.
