turnip: Try harder to keep LRZ valid and fix a few edge cases

Danylo Piliaiev requested to merge Danil/mesa:turnip/feature/more-lrz into main

Refactored tu6_calculate_lrz_state and added comments.

  1. If there is no depth write we could keep LRZ valid with any compare op, we just have to temporary disable LRZ for incompatible ops in such case.

  2. Found that VK_COMPARE_OP_EQUAL is not compatible with LRZ, and since it doesn't change LRZ buffer - LRZ could be just temporary disabled. This fixes rendering of grass/trees in PUBG mobile on angle.

Closes: #6127 (closed)

I should test it better and eyeball a few more times.
