tu: Disable LRZ when resuming if the GPU doesn't support tracking

Browse source 
We rely on tu_lrz_flush_valid_at_suspending_rp_boundary() to make sure
that subsequent resuming renderpasses get the correct LRZ state. However
this doesn't work on early a6xx GPUs without tracking support. Disable
LRZ in this case, similar to secondaries.
