During metrics initialization we load a few uncached glyph widths which can occasionally
show up in a profile. This should reduce the overhead of that somewhat.

People keep adding useless null-checks and it was not clear what the consensus
was from bug 1441165, but this should be unobjectionable I guess.

Our implementation modified the state, in addition to throwing the exception.
And the tests not only didn't test for this, but wouldn't have reached that
code anyway, due to the harness giving up as soon as anything failed.

It doesn't really make sense to enforce this behavior for calls on stack
variables (which presumably we then want to do something with) and doesn't
necessarily make sense to enforce it for member variables either.

To avoid needing to access JSScript::realm() during finalization, we
associate the LCovSource* with a JSScript (if coverage is enabled). This
also saves memory by avoiding cloning the filename for each inner
function. One semantic change here is that the LCovRealm/Source is
allocated sooner than previously, but the result is the same.

Refactor the ScriptNameMap code to put more of the logic in the
code-coverage sources instead of the JSScript sources. Also make
JS::Realm::lcovRealm use an accessor function to allocate as needed.

To prepare for later patches, track writeScript OOMs as a flag inside
LCovSource. This flag is checked when merging the LCovSource into an
LCovRealm. This allows us to avoid handling errors while finalizing
JSScripts.

Tasks dispatched from RunInStableState() can be cancelled if there's a load in
between, so this is not sound.
See nsSyncSection::IsCancelled().
This is the only patch in this bug that is worth uplifting IMO.

Instead, rely on the proper initialization of `mWrapColumn` via
`nsPlainTextSerializer::Init`.
This will allow to move `mWrapColumn` to `nsPlainTextSerializer::Settings::mWrapColumn`,
simplifying reasoning about it.

`TextEditor::SetWrapWidth` already sets `nsIDocumentEncoder`'s wrap
column which is propagated to `nsPlainTextSerializer`. So this should be
a safe change.

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.
