drm/xe/pf: Fix VF config validation on multi-GT platforms
When validating VF config on the media GT, we may wrongly report that VF is already partially configured on it, as we consider GGTT and LMEM provisioning done on the primary GT (since both GGTT and LMEM are tile-level resources, not a GT-level). This will cause skipping a VF auto-provisioning on the media-GT and in result will block a VF from successfully initialize that GT. Fix that by considering GGTT and LMEM configurations only when checking if a VF provisioning is complete, and omit GGTT and LMEM when reporting empty/partial provisioning.
