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.

This was set to 30 seconds on Nightly in 2016, but it was never
enabled for release builds, so let's at least make it consistent.

This eliminates all of the thread leaks we had on record, while also increasing
our coverage on the code that's used for testing firefox.

This is a backout of b635c277c9f4 (bug 1675138).
It seems that the CRLite certificate transparency ingestion machinery is
missing certificates it should know about, which means that false positives are
possible, which means that users are seeing revoked certificates where they
shouldn't. This patch sets CRLite back to telemetry-only mode while the
infrastructure gets fixed.
