turnip: Implement unidirectional LRZ for A7XX

Mark Collins requested to merge PixelyIon/mesa:a7xx-lrz into main

Adds support for unidirectional LRZ on A7XX, the performance uptick was confirmed to match the proprietary driver in the range of lower single digit percentage improvements (2.2% on 3DMark Wild Life Extreme). This passes all of VK-CTS including custom tests made for specifically testing LRZ since it's mostly not enabled on regular VK-CTS tests, it's been additionally tested on a variety of games and demos where rendering also seems to be fine when forcing LRZ.
