drm/xe/pat: sanity check compression and coh_mode

There is an implicit assumption in the driver that compression and
coh_1way+ are mutually exclusive. If this is ever not true then userptr
and imported dma-buf from external device will have uncleared ccs state.
Add a build bug for this so we don't forget.
