Migrate mesa to llvm 10

[Timo Aaltonen]

[Impact]

Mesa should migrate to llvm 10. Focal didn't migrate to it before release, because there was a build issue on ppc64el, which has since been fixed.

[Test case]

Test AMD graphics and/or qemu desktop after installing migrated packages.

[Regression potential]

This has been in Debian for a month now without issues.

this was already fixed in groovy by 20.0.7-1ubuntu1
