This patch enables EGL robustness with WebRender. It also tries harder
to get RBAB, favouring KHR+RBAB over EXT-RBAB, as testing with Intel and
NVIDIA Mesa drivers on Ubuntu suggests we can get KHR+RBAB but not
EXT+RBAB. It also adds support for requesting NVIDIA specific resets via
EGL_NV_robustness_video_memory_purge.

There are some complications here to handle unpackaged and packaged
builds. In addition, there could be a difference between App prefs
and GRE prefs. Since the underlying backgroundtasks code is built as
part of Gecko (i.e., `toolkit/...` rather than `browser/...`) I have
favoured GRE prefs. I think, however, that what is written will work
for App-specific prefs, but I'm not concerned with that detail at this
time.
This also add tests for backgroundtask-specific prefs, which are
structured as both xpcshell and mochitest-chrome tests because
locally, the former tests unpackaged builds and the latter can
accommodate testing packaged builds. We could use mochitest-chrome
for both, but this has been pleasant to work with locally.

As we make the transition to using EGL over GLX, we will need our
detection code to be sufficient without EGL to determine the device in
use. This patch makes us always use the EGL testing code over the GLX
testing code, regardless of the pref/envvar setting.
At the very least, we need to know the vendor ID of the device in use.
We can determine this if there is only one GPU on the PCI list, if we
get a driver name from Mesa, or if it is a proprietary driver (i.e.
NVIDIA) which includes its name in the vendor ID. If we know the vendor
ID, we can usually derive the device ID from the PCI list.
We now also track which path glxtest took. If we successfully did the
test via EGL, then we will allow the pref/envvar to use EGL instead of
GLX. If the test reverted to GLX, then it will use GLX regardless of the
pref/envvar. This is necessary because we need to know if the libraries
are available or not -- some systems may be missing one or the other.

This allows us to default to skipping the bundled Twemoji Mozilla font when running on Win8.1 or later,
where we can assume Segoe UI Emoji is available.
The new pref here replaces the existing pair of boolean prefs that were only supported on Android,
and is now respected on all platforms. Available settings are:
0 disable use of app-bundled fonts
> 0 enable use of app-bundled fonts
< 0 default (auto): decide at startup, based on the system environment
(The pref is relevant only at startup; changing its value during a session will not make the bundled fonts
appear/disappear dynamically.)

Flips the `javascript.options.use_off_thread_parse_global` pref to false.
In this mode, off-thread JS parsing will parse to Stencil and hand that back
to main-thread to instantiate. This removes the `mergeRealms` operation and
more importantly removes restrictions involving atoms-zone GC. This addresses
intermittent stalls that can previously occured where certain incremental GCs
would disable all off-thread parsing for a short while.
Additionally, this switches the JSBC data format from a legacy format to one
based around the Stencil data structures. As a performance consideration, we
currently continue to use the off-thread parse-global for decode operations.
If the GC prevents us from doing this, we simply instantiate the Stencil on
main-thread like for the parse case. Further performance tuning will allow us
to revisit this again in future.
Note that the privileged ScriptPreloader that runs during process startup
still uses the legacy format at this time.
We also change the defaults of the js-shell which requires updating various
help messages.

Warp doesn't use this and there's a lot of complexity to support recompiling
an IonScript while continuing to use the current one.
It might make sense to add a similar hot tier to Warp at some point, but because
Warp uses trial inlining the implementation would likely be pretty different:
we could invalidate, flag the JitScript as supporting different inlining thresholds,
and go back to Baseline to gather information.
