Upgrading Ubuntu 22.04's Kernel & Mesa For Better AMD RDNA2 Performance

Dawn of War 3 was also showing off nice RDNA2 performance uplift when pulling in the Linux 5.17 kernel.

F1 2021 didn't show much change with these Radeon graphics driver upgrades.

Meanwhile for some titles like HITMAN 3 there simply wasn't any measurable improvement for this mid-range Radeon RX 6000 series graphics card across the Mesa and kernel versions tested.

It was a bit concerning though seeing the peak frame time spiking on Linux 5.7+ for this RDNA2 GPU.
