This patch tunes maximum threads-per-threadgroup and threads-per-block for faster renders on Apple GPUs. Appropriate tuning is selected based on the GPU architecture (M1 or M2). We see a benchmark uplift of around 5-10% on M1 family chips. Similar uplift is expected on M2 with upcoming OS changes. (Ref T101931)
