The 3-tier PGO builds used a separate mozconfig called 'profile-use' for
the final tier. This created a problem when it rode to beta, since the
same mozconfig was used for all trees, which meant we ended up with
nightly branding on beta builds.
With the PGO-enabling logic in common mozconfigs, we can enable it by
setting the MOZ_PGO_PROFILE_USE environment variable from the task
definition. All of the final-tier PGO builds now use the nightly, beta,
etc mozconfigs like before, so branding should be intact.

We would like to switch to using cross-language LTO on all of our
platforms, and we need to use a beta version of Rust on Mac to do that.

This allows users to set TASKGRAPH_OPTIMIZE_STRATEGIES to a
python_path.find_object string. E.g:
TASKGRAPH_OPTIMIZE_STRATEGIES="module:strategies" ./mach taskgraph optimized
This opens the door to swap in external strategies at runtime and will be
used for back testing experimental strategies.

Incremental effort to improve android-hw device availability: Stop running android-hw
debug jsreftest and jittest on integration branches.
Also, remove the option for android-hw opt jittest on try. opt is a nice alternative
to pgo on try in general, but the risk of accidental (unnecessary) inclusion in
try pushes makes this a luxury we cannot afford on android-hw.

This follows the model set down for EME artifacts:
- a new tier is added that uses a new Python build action to fetch and
artifacts
- the action unpacks the fetched artifacts and moves specific inputs
into places expected by the build and packager
- in automation, MOZ_ARTIFACT_TASK* is used to ensure the artifacts
come from the correct tasks
In this case, the artifact fetching is done entirely in a new Python
build action that internally uses `mach artifact install --job ...`.
The action also verifies that the fetched artifacts are compatible and
that we're not assembling a fat AAR that is nonsensical. The specific
inputs are not used in the Fennec APK that is produced; they're only
used in the GeckoView AAR that is produced.
The artifact fetching itself required tweaking to fetch only
`target.maven.zip` artifacts and to not unpack them.
The specific inputs used are the native libraries (libs/$ARCH/*.so)
and the architecture-specific preference files ($ARCH/greprefs.js and
defaults/pref/$ARCH/geckoview-prefs.js). None of these inputs are
impacted by l10n.

Taskcluster didn't correctly apply the change back to tier-3 in the previous patch because the wildcard setting the tier to 2 by default beat out the specific line setting tier-3 for the geckoview tests. This patch specifically changes the tier for non-geckoview reftests (fennec runs on x86 emulators) to tier-2, while geckoview reftests (TRA runs on x86_64 emulators) to tier-3.
This change also explicitly sets the non-reftest tests to tier-2 for all android platforms, because they didn't have the permafails that the reftests seem to have.

Some debug info for system packages are not available to valgrind in the
valgrind docker image, some of which are for libraries actively used by
Firefox. Not all of them, unfortunately, have debug info available, but
some of them do and we add them all. We could skip a few that are not
really useful, but that doesn't make a significant difference to the
docker image size (~0.3%).
