This change is a continuation of Part 1 (Bug 1570128), where the 2D content rendered by Firefox for Firefox Reality on Desktop is marshalled through VRHost so that it can be presented in a VR environment.
A new class, FxrOutputHandler, is created to manage creating a sharable texture, sharing it through VRShMem, and updating it when content updates. This class updates content with both WebRender and conventional rendering output.
This initial iteration of FxrOutputHandler does not have synchronization between reading and writing this shared texture across processes. A subsequent fix (Bug 1581881) is pending, which will reuse WebVR code to manage writing to and reading from a pool of textures.
This also presents issues with rendering protected media, so an additional class, FxrWindowManager, is created to manage all windows created for Firefox Reality on Desktop so that it can inform whether or not protected media can be presented.
The automated manual tests in vrhosttest.cpp now show the real shared texture handle rather than a fake value, which shows that marshaling succeeded.

Also while doing it:
* Ensure activity observers get notified after visibility is computed already.
This is how we notify all other activity observers already, and we are
double-notifying in the case we actually get a page show _and_ a visibility
change, but this is a pre-existing problem.
* Remove special-cases for InFrameSwap() from MediaRecorder. Now that pagehide
doesn't mess up with our visibility state the regular check just works. I
ensured I didn't regress bug 1444541.
* Had to fix a UITour test that relied on the visibility changing back and
forth for the detached tab. It seems there's no real place in UITour that
listens to that event so we should be good.
* Added tests, verifying that they both fail without the patch.
After this we can remove nsDocShell::InFrameSwap(), as the only caller is the
assertion, but I wanted to keep it regardless, at least for now, until this
patch has been in for a bit.

Note that the areas are clipped out by all ancestor scroll ports and
their coordinate systems are the screen coordinate. So that we can tell
arbitrary elements in out-of-process iframes are scrolled out or not with
this area and the transform matrix of the iframe on screen coodinate.

This also renames the existing infallible nsDocShell:GetBrowsingContext()
getter to BrowsingContextRef(), and changes the return type, since several

Currently, TabGroups know to break their reference cycles only when the last
window leaves them. For TabGroups which have never had a window join (which
happens under Fission), this means they also never see a window leave, and
therefore never break their reference cycles, and leak.
This patch adds a check to break reference cycles if no windows have joined by
the time a BrowserChild they belong to is destroyed.
MANUAL PUSH: Lando fails to rebase.

This is the first step in making it possible to return remote WindowProxy
objects from window.open() and related APIs.
This patch also incidentally fixes a bug where getContentWindowOrOpenURI
returned the top-level browser window rather than the new content window when
passed OPEN_NEWWINDOW for the `aWhere` parameter. This was not the expected
behavior, and was a potentially major footgun for any new users who expected
to always get the content window for the URL they were loading, rather than
sometimes getting a chrome browser window instead.
For now, that case just returns null, which is only a minor footgun, rather
than the major one we had before.

I just early-returned rather than only skipping the PaintWhileInterruptingJS

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.
