If the run task generates bad profile data, the merge step in the
profile-use task will fail. However, retrying the profile-use task
doesn't fix the problem, and there isn't a straightforward way to retry
the run task in this situation. Instead we can add a clang toolchain to
all the run tasks, and perform the merge there.
This means the output from the run task will always be a successfully
merged file called 'merged.profdata', and we no longer need to perform
the merge as part of the profile-use build as a GENERATED_FILES step.

There was quite a bit of discussion of this in `#build` on IRC,
and the consensus was that geckodriver should be built as a
stand-alone Rust crate and not as part of Firefox/Gecko (say, as a new
--enable-project target). This follows that approach, and the
expression, modeled off of cbindgen but updated to cross compile from
a Linux host to all targets, is pretty straight-forward.
A sparse profile would be nice, but the way that the Gecko Cargo
workspace works means that the profile must accumulate Rust code from
many locations.
If we want to, eventually testing/geckodriver can be removed from the
top-level Rust workspace, the geckodriver-signing tasks migrated to
these toolchain tasks, consumers migrated to the signing tasks, and
geckodriver removed from the "common" test archive.

The remaining uses all need adjustements to in-tree mozconfigs, so they
all need to be done at once.
However, to make things slightly more intelligible, we do this in two
steps. This is step 1: we modify the use_toolchain transform to take care of
the transformation, while keeping the task definitions intact, so that
we only deal with mozconfig and build script adjustements here.

Now that all GCC and related source tarballs extract to paths
independent of their version number, the scripts are all very
look-alike, so they can be consolidated.

Bug 1479533 was proposing to add a similar functionality, but this
iteration avoids actually unpacking anything, and ensures
reproducibility by relying on the reproducible bits from the original
archives: file ordering, flags, etc. (since they are checksummed, those
are never going to change for a given archive).
Another notable difference is that this applies the repack on the fetch
task itself, rather than create a separate task to apply the repack. The
latter has advantages, in that it allows to change the repacking without
redownloading the original file from a third-party server, but in
practice, most changes to the repacking would trigger the download tasks
anyways.
This patch only takes care of changing the archive type (zip->tar), and
the compression type (anything->zstandard).

What this means is that the sources for clang/llvm are downloaded
separately from the toolchain build (which also means we finally only
download a given version of clang once for all platforms).
In turn, this means the build-clang.py script needs to start with an
existing llvm-project tree, and we choose to make build-clang.py expect
that it's run from the llvm-project root directory.
This also means we don't need to download git for the windows toolchain
task.

MANUAL PUSH: avoid closing autoland while toolchains are rebuilt.
This removes the need for the hacks in wr-macos-cross-build-setup.sh and

Plenty of places use `nproc`, and only a couple use `getconf
_NPROCESSORS_ONLN`. Use the former instead of the latter.
