panvk: Rebase onto mesa/main
Note that panvk2_{buffer/image}_view
and panvk2_sampler
were removed so that Valhall can use the panvk*
versions. 539ccfde and 015307c7 were adapted from https://gitlab.freedesktop.org/bbrezillon/mesa/-/commits/panvk-cleanup-2.
6057483b and 0b200852 required a lot of modification due to file structure changes from mesa/main.
