turnip: apply workaround for depth bounds test without depth test
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
blob_a630_vs_a650_dEQP-VK.dynamic_state.ds_state.depth_bounds_1.tar.gz
(pay attention to the last A6XX_RB_DEPTH_CNTL
, in that draw depth test is disabled but depth bounds test is enabled)
Also rename Z_TEST_ENABLE->Z_READ_ENABLE and Z_ENABLE->Z_TEST_ENABLE along the way, to make it's less confusing.
