[dxvk] Introduce tracking ID for resource tracking

Browse Source 
Replaces the existing bit masks, which is possible now because the
CS thread is the only place where submissions happen now.

This way we only count each resource once per submission, or twice
in case a read access is followed by a write.

This also fixes a potential tracking bug with shader-writeable resources.
