Add Crocus instead of i965

[ticotaco72]

i965 is retired as of https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/10153

The change still didn't happen in master and the linked MR doesn't change features.txt. So for now I can't do much about it, but yes, I will do the changes as soon as it is made in the features.txt file.

i965 driver was just removed from features.txt, crocus and iris added: https://cgit.freedesktop.org/mesa/mesa/commit/?id=aa20ea7c5e58508a07964f19cb8570c3113156cb https://cgit.freedesktop.org/mesa/mesa/commit/?id=125700cf8b87c4ddd6ec881783d0363d996a8b82 https://cgit.freedesktop.org/mesa/mesa/commit/?id=45a0de84912dfbb9290f5b97595ae8a1478b69bd mesamatrix misses iris and crocus.
