Draft: nvk: EXT_depth_range_unrestricted support
This is an initial attempt at VK_EXT_depth_range_unrestricted
It doesn't fully pass CTS
./deqp-vk --deqp-case=dEQP-VK.pipeline.monolithic.depth_range_unrestricted*
Test run totals:
Passed: 1812/2028 (89.3%)
Failed: 216/2028 (10.7%)
Not supported: 0/2028 (0.0%)
dEQP-VK.pipeline.monolithic.depth_range_unrestricted.depthclampingdisabled.d16*
dEQP-VK.pipeline.monolithic.depth_range_unrestricted.depthclampingdisabled.d24*
I've hunted around to noavail here, but maybe someone can get an idea or maybe if I come back to it later I'll make sense out of it.
