intel: Describe modifier compression with booleans

Replace the aux_usage field with two booleans: one for render
compression and one for media compression.

This more accurately describes how CCS_E is used on gfx12. On those
platforms, the FCV feature may be enabled or disabled, but ISL's
modifier table has been using the FCV aux-usage for every gfx12 render
compression modifier. Instead, set the newly-added render compression
boolean to true.
