We might want to do this on Windows 11 as well, but Windows 11 has a
system-wide preference with UI so let's not do that just yet at least,
UI-exposed preference.

Within DrawTargetWebgl, this implements a SharedContext class to store both the WebGL context and
also related resources for drawing with it. Not a lot of new code has actually been added as this
was mostly accomplished by refactoring as much drawing code as possible that touched the WebGL
context to be moved into SharedContext, while leaving any code that was only dealing with Skia
software rasterization still within DrawTargetWebgl itself as well as individual framebuffer state
that is unique to each DrawTargetWebgl instance.
Before DrawTargetWebgl can use SharedContext to draw, it must use SetTarget to install its framebuffer
as the one that the WebGL context will draw to as well as to learn details about the viewport and
other per-framebuffer state. All of the high-level cache state that was previously on DrawTargetWebgl
has now moved into SharedContext, so that SharedContext can easily access this for drawing as well
as to provide for the goal of simplifying resource limiting.

This patch adds a pref "signon.usernameOnlyForm.formThreshold" to limit
the number of form we processed while receiving "PWMGR_NUM_FORM_HAS_POSSIBLE_USERNAME_EVENT_PER_DOC"
event. This improves the performance while loading a page with multiple username-only likely form.

The `media.clockdrift.buffering`'s type was set to signed integer when
introducing `AudioDriftCorrection` in Bug 1637234 (D74884), but the
buffering type of the `AudioDriftCorrection` was changed to unsigned in
Bug 1656438 (D89777). The `media.clockdrift.buffering` should be updated
to the unsigned integer as well.

This is designed to mitigate the problem of third-party fonts that render poorly
under DirectWrite's bold simulation, by using multi-strike synthetic bold (like
we use on macOS) instead.
The behavior is controlled by a pref, so that we can readily switch between
using DWrite's bold simulation for all fonts (pref=2, our current behavior);
using it only for installed fonts and falling back to multi-strike for webfonts
(pref=1, new behavior); or never using the DWrite simulation (pref=0).

This is faster and more straight-forward code than the old
ShouldUseDarkScrollbar shenanigans, and allows to have dark-themed
scrollbars.

Firefox version 100 will ship on 2022-05-03. The Webcompat team can use Firefox's site interventions to spoof a version 99 UA for individual sites broken by a three-digit version number. But Firefox’s site interventions can’t override the UA for enterprise intranet sites we don't know about.
This patch adds a new "network.http.useragent.forceVersion" pref that enterprise admins can set to a known-good UA version (like 99) in an enterprise policy file. If the pref has a non-zero value, then override the User-Agent string's Firefox version. The value 0 means use the default Firefox version.
We can remove this pref in Firefox 103 after the next ESR is branched (version 102 on 2022-06-28). Enterprise users can use ESR 102 with forceVersion pref = 99 until the next ESR in mid-2023. Hopefully they can fix their broken intranet sites by that time.
