Use apt for more PETSc packages on x86

Description

We can use the apt binaries for a load more PETSc packages.
Works locally for x86. Will try with aarch64 once it works with x86 on CI.

You can "test" ARM by forcing GitHub actions to rebuild the containers like I do in #4104.

Just make sure to give them a unique tag.

Do we have an ARM label to specify the runner?

[connorjward]

Sort of. We use the macOS runners. I was suggesting rebuilding all of the containers, which will hit the ARM build.

I figured out why the Docker build is failing! It's sed: https://github.com/firedrakeproject/firedrake/blob/master/docker/Dockerfile.vanilla#L46. We overwrite COPTFLAGS and such to pass -mtune=generic so your extra settings aren't propagated. Could you maybe figure out a better bash command to just replace -march=native with -mtune=generic?

Just had a go at a fix for this.

UNDO BEFORE MERGE

[connorjward]

Looks 99% good to me. Ready to merge once these changes are committed.

Forcing through as only failing due to a docs linkcheck fail.
