turnip: R8G8 fixes

Danylo Piliaiev requested to merge Danil/mesa:turnip/fix/prevent-r8g8-non-ubwc-tiled into main

Non-UBWC tiled R8G8 is probably buggy since media formats are always either linear or UBWC. There is no simple test to reproduce the bug. However it was observed in the wild leading to an unrecoverable hang on a650/a660.

Closes: #5926 (closed)

@robclark Maybe Freedreno also needs this fix?

R8G8 have a different block width/height and height alignment from other formats that would normally be compatible (like R16), and so if we are trying to, for example, sample R16 as R8G8 we need to demote to linear.

Follows the fix in Freedreno: b97e3bb2
