tu: Enable UBWC for D24S8 with USAGE_SAMPLED and formatless border color

Danylo Piliaiev requested to merge Danil/mesa:turnip/feature/ubwc-for-sampled-d24s8-w-dxvk-vkd3d-proton into main

What does this MR do and why?

DXVK and VKD3D-Proton use customBorderColorWithoutFormat and have most of D24S8 images with USAGE_SAMPLED, in such case we disable UBWC for correctness. However, games don't use border color for depth-stencil images. So we elect to ignore this edge case and force UBWC to be enabled.
