Bug 1887029 - Simplify TabAttributes to explicitly specify supported attributes, r=sessionstore-reviewers,sfoster,dao, a=dmeehan

The only tab attribute which is ever persisted by SessionStore is
"customizemode". This patch limits the logic to only allow persisting and
restoring this attribute.

The browser_attributes.js test is also updated to use the "customizemode"
attribute for testing, rather than a custom specified attribute.

Bug 1878199 - patch 2 - If the FontFaceImpl has a user-font entry, hold its lock during Add/Remove font-set operations.  a=dmeehan

This should fix the intermittently-reported race here, by ensuring that access into
the FontFaceImpl from GetUserFontSets(), called by the main thread, cannot race with
changes being made by the AddFontSet()/RemoveFontSet() methods.

(If the FontFaceImpl doesn't have an mUserFontEntry yet, then these methods don't
need to lock, as only the owning thread will be touching it.)

Bug 1878199 - patch 1 - Don't create an additional Mutex in FontFaceImpl::Entry, just use the base gfxFontEntry's existing RWLock.  a=dmeehan

No functional change here, just cleanup in preparation for the following patch.
We don't need FontFaceImpl to create a mutex, as there's already a lock (RWLock)
in its base class gfxFontEntry, and we can use that to guard the fields here.

When a background page and service_worker are specified simultaneously,
load the background page instead of neither (i.e. the bug).

This patch only fixes the issue when
extensions.backgroundServiceWorker.enabled is false; When true, the
service worker is expected to load but doesn't due to
https://bugzilla.mozilla.org/show_bug.cgi?id=1775618#c1 . That requires
a different fix and is therefore saved for a follow-up.

The last use of importing the whole __builtin__ module was removed in
bug 1264831... 7 years ago.

Now that it actually doesn't work anymore with recent releases of
cpython, we might as well kill it for good.

Bug 1839263 - Don't derive assertRaisesFromLine from assertRaises. r=firefox-build-system-reviewers,ahochheiden, a=test-only DONTBUILD

In python 3.11 (maybe also 3.10, I haven't tested that version ; 3.9 was
definitely different), by the time the context manager comes back in our
assertRaisesFromLine, the traceback is not available anymore (or yet,
I'm not entirely sure which way it does) to inspect and check the line
numbers we want to check.

And while assertRaises exposes the thrown exception in its `exception`
attribute, it also resets the traceback associated with it, so we can't
find it there either.

So instead, we implement our own context manager for
assertRaisesFromLine such that we can access that traceback.
