Having `rustc` be `rustup`'s wrapper for `rustc` means that we may
silently honor `rustup`'s override mechanisms. We noticed this first on
OS X, where we use the "real" `cargo` but `rustup`'s `rustc` wrapper,
and problems ensued when `cargo` thought it was using one version of
`rustc`, but actually wound up using something different.
It seems better to avoid silently interposing `rustup`'s toolchain
override mechanisms everywhere, rather than having to special-case OS
X. So let's factor out a general mechanism for removing the wrappers
`rustup` provides and use that for both `rustc` and `cargo`. The tests
need adjusting because we weren't triggering the unwrapping cases
before; we don't yet test the case where we really do need to unwrap.
That test can be left for a future patch.

We've not been checking the clang-cl version in use. This lack of
checking is bad, for a couple of reasons:
* Released versions of clang-cl differ drastically in their robustness;
* Only the most recent version of clang-cl supports aarch64.
We should check for a minimum version of clang-cl, just like our other
supported compilers. As a bonus, we can then start depending on
features that we know appear in the particular minimum clang-cl
version. (The current patch is motivated by `/clang:` command-line
support, but one could pick other things.)

We already do this for the compiler that we detect via
toolchain.configure...but as the comment in `basic_bindgen_cflags`
alludes to, we don't actually use that compiler here. We use a much
more bare-bones compiler, so we have to add the necessary flags manually.
We need to make `--with-macos-sdk` a `js_option` so that uses of bindgen
in the JS engine will receive the proper flags.

[browsertime](https://github.com/sitespeedio/browsertime) is a harness
for running performance tests, similar to Mozilla's Raptor testing
framework. The Performance Team is using it locally with some
success, but we're running a heavily modified toolchain that is
challenging to install. This mach command is intended to be leverage
for getting more folks able to use browsertime easily.
In particular, the version of browsertime that this installs has
nalexander's changes to support testing GeckoView-based vehicles. If
this approach meets with approval, I'll continue to follow-up with
additional configuration and tooling layers to make it even easier to
drive GeckoView-based vehicles.
I elected to piggy-back install on the eslint installation process,
since this is very similar. To that end, I generalized what was there
very slightly. I elected not to try to move the existing code into a
more obvious shared location, although it might be possible, because
it wasn't clear what contexts the existing code would be invoked
from. In particular I wasn't certain the code could rely on a
complete mozbuild checkout.
I did need to ensure the local Node.js binary is early on the PATH;
this was an issue I ran into with my initial Node/Yarn prototyping
many months ago. At heart the issue is that package scripts in the
wild invoke a bare `node` or `npm` command; if there was a culture of
invoking $NODE or $NPM, this wouldn't be necessary. There's no harm
doing it for ESlint, and it will help the next person who wants to
install an NPM package for tooling in this manner.

this change comprises the in-tree changes required to make use of sccache in gcp.
specifically:
- a gcp metadata lookup for availability-zone is added to mozconfig, enabling a build to determine its regional gcp sccache bucket
- the sccache cargo build command is modified to include the gcs feature when the environment contains gcs configuration
note that further changes are required on infra to support sccache use. the required changes already [exist](https://github.com/mozilla-releng/OpenCloudConfig/commit/1d515dc) and are enabled for gcp windows infra, including:
- a json credential file on the build instance filesystem, containing credentials valid for the appropriate scm level bucket for the gcp region
- an `SCCACHE_GCS_KEY_PATH` env variable containing the path to the json credential file
- an `SCCACHE_GCS_RW_MODE` env variable containg the text `READ_WRITE`
- sccache buckets must exist for each region and scm levels 1 & 3
- credentials for scm level 1 buckets **must not** be valid for scm level 3 buckets
on gcp systems which do not contain credential files and the above mentioned env variables (eg gecko-[1-3]-b-linux), sccache should fail gracefully without breaking builds.

which happens to be the final stage for our android runtime libraries
build. But we may also want to build runtime libraries on 3-stage
bootstrap builds, in which case we don't want compiler-rt to be active
for the second stage. Move the setup into build_one_stage so that the

Before this patch, we first find an executable, then check the version. So if
the first executable we find is outdated, we won't look for others.
Instead, check each of them for different versions manually. This will also

a cbindgen with the right version.
