On some GPUs when:
- depth bounds test is enabled
- depth test is disabled
- depth attachment uses UBWC in sysmem mode
GPU hangs. As a workaround we should enable z test. That's what blob
is doing for a630. And since we enable z test we should make it always pass.

Blob doesn't emit this workaround on a650 and a660. Untested on a640.

Fixes:
 dEQP-VK.pipeline.extended_dynamic_state.two_draws_static.depth_bounds_test_disable
 dEQP-VK.pipeline.extended_dynamic_state.two_draws_dynamic.depth_bounds_test_disable
 dEQP-VK.dynamic_state.ds_state.depth_bounds_1
