iris: Prefer more GPU-based uploads for compression

Browse source 
Where possible, start compressing depth and stencil resources on upload.
This makes a couple of benchmarks (CS:GO, GFXBench5's gl_alu2_off) start
sampling HiZ buffers in a compressed state instead of the pass-through
state.

Improves the FPS of GFXBench5's gl_alu2_off by 3.14% ±0.52% on TGL.
Testing was done with the performance CI.
