Upgrade to Julia 1.11

[charleskawczynski]

This PR upgrades us to Julia 1.11, and lifts some of the conditionals.

Closes #2030

[charleskawczynski]

We were able to sidestep JuliaLang/julia#56295 by dispatching from Base.copyto! directly, so we can still overload getindex on linear indices. The commit where we originally saw this issue, 9795581, had a different dispatch pattern in Base.copyto! for datalayouts. The main branch is dispatching more carefully.

[charleskawczynski]

The only remaining issue is that there is still a compile-time regression, but perhaps that's okay with us since we're using the depot.

[Sbozzolo]

I don't think we should remove the checks for versions prior to 1.11: we still want to be able to run with 1.10

[Sbozzolo]

Thank you!

[charleskawczynski]

Ah, this requires changing the github status, that's why the required checks aren't starting.

I think JET, which is used in the test suite, is not yet compatible with Julia 1.11. So we may need to wait for that afterall. (at least in ClimaCore CI).

Could you paste a link to the error? I don't see clear signs in the repo for JET saying that it is not compatible with 1.11 (but I can totally believe that it doesn't work)

Interesting. I can install JET locally in my base env with 1.11.2, but not in the climacore enviornment. It probably conflicts with something else. I can look into this

[Sbozzolo]

I think I found it! SnoopCompile was pinned to 2 (3 is available)

[Sbozzolo]

Yes, it was SnoopCompile, which force JET to use version 0.8 instead of 0.9. I pushed a new commit with the updated Manifest.
