Add zig linker support

[RossComputerGuy]

Adds support for Zig's linker (zld)

Merges #13493, #12293, and #12953.

Context from #13493 (comment)

What we really need here is to have a single PR that contains all the necessary changes:

* this patch

* the patch from [linkers: basic support for the 'zig cc' linker #12293](https://github.com/mesonbuild/meson/pull/12293)

* a patch to enable zig in the CI workflows, see [Add Zig to ubuntu-rolling image, CI test #12953](https://github.com/mesonbuild/meson/pull/12953)

And a second PR that adds zig to the CI images without adding it to the CI workflows, see #12953 again.

Currently everything is spread out quite a bit and it's difficult to get a handle on whether it all works.

Please don't use merge commits.

We will NOT merge any PR that contains one.

Sorry, didn't know that one. Should I squash/cherry pick instead?

[thesamesam]

I'm not sure if we want to pull master for this. That'll lead to flaky CI. If we do want that, it needs justification.

[RossComputerGuy]

Yeah, we can probably use the latest release instead of master. I just need to figure out the jq to read the 2nd object.

[RossComputerGuy]

Alright, we're now using a tagged release instead of master.

Zig is in the CI image now, I think, so this just needs a rebase and dropping that last commit?
