This upgrades the default version of zig to zig_0_12, which builds
reproducibly on darwin.
Fixes#299091.
Also upgrades all packages compatible with zig 0.12 to that version.
I tried to upgrade packages currently pinning 0.11 as well, but only a
few worked.

While the word 'simply' is usually added to encourage readers, it often has the
opposite effect and may even appear condescending, especially when the reader
runs into trouble trying to apply the suggestions from the documentation. It is
almost always an improvement to simply drop the word from the sentence.
(there are more possible improvements like this, we can apply those in separate
PRs)
Projects building with meson are currently installTargets. Map these
to install tags, which are roughly equivalent. This allows projects to
selectively install components.
Meson now comes with its own set of commands for building, testing,
installing etc., that by default wrap around Ninja. The reason to
prefer using the Meson commands is that they take additional
options (e.g. setting custom timeouts for tests — my motivation for
this change).
Here, I've modified the Meson setup hook so that Meson's test and
install commands will be used instead of Ninja's when Meson's
configurePhase is used. This restriction is to avoid starting to run
Meson directly when dealing with custom build systems that wrap around
Meson, like QEMU's. We don't use meson's compile command, as it just
runs ninja, and that's handled fine by the existing Ninja setup hook.
Naturally the Meson commands don't support entirely the same set of
options that the Ninja ones did, but I checked through Nixpkgs to find
any packages using Meson that used any options that wouldn't be picked
up by this new system. I only found one, and it was just setting
checkTarget = "test", which is the default value for Ninja and has no
Meson equivalent (because we directly tell Meson to run the tests
rather than going through a generic job system like Ninja).

Add this hook to checkPhase to allow for running MPI application in
the sandbox. It detects the MPI implementations and sets the respective
environment variables.
Zig is still under active development, and new releases often introduce
breaking changes. This makes updating the default version of zig easier.
Some packages did not receive this change because they could be using
the c compiler or linker of zig, which doesn't receive as much breaking
changes compared to e.g. the zig std library.

also updates nixdoc to 2.3.0. the nixdoc update is not a separate commit
because that would leave the manual build broken for one commit,
potentially breaking bisects and rebases.
skipping heading levels (eg from # to ###, or starting at ###) is legal
in pandoc, but not in nixos-render-docs. pandoc acts as though section
levels *were* consecutive, nixos-render-docs prefers to tell people not
to do that kind of thing because it can make documents more fragile.
pandoc drops .title classes when rendering to docbook, so these are
effectively just paragraphs anyway. without support for including them
in a table of contents the complexity of parsing them in
nixos-render-docs won't be warranted.
