... in the "fails because test keys are not configured case".
It looks like one of the real-life keys got a short ID of 0x12,
so the "key ID isn't what the test configures" failed about a fifth
of the time... so change around the test ID to avoid it.

Add WPTs for RelOpenerBcgDependencyHint

Add tests which confirm that rel=opener on anchors and an opener window
feature with window.open() prevent proactive browsing context group
changes. These tests are tentative, since the associated proposal has
not shipped.

These tests are implemented by using a named window lookup after a
session history navigation to verify two pages are in the same
BCG (since the lookup is scoped to BCGs).

Also set RelOpenerBcgDependencyHint's status to experimental. The
feature is needed for these tests to pass.

Add WPTs for named window lookup and BCG swap limits

These tests verify the behaviour discussed here:
whatwg/html#10818

While there is some implementation defined behaviour, we can add tests
for the behaviour that's consistent between the major implementations,
namely that proactive browsing context group swaps can't be done while
another context exists in the group, that named lookups are scoped to
browsing context groups, and the lookup order in the case of multiple
contexts with the same name.

Implement PaintTimingMixin for element timing

Remove PaintTimingCallbackManager, and instead use the
PaintTiming presentation callback for element-timing and LCP.

For now, only element timing exposes PaintMixin, LCP will be
done in a follow up.

To avoid a big refactor, element timing and LCP are still using
callbacks like before, and MarkPaintTimingInternal integrates
with those.

Regarding the removed TODO: checking one non-null namespace should
suffice, since other non-null namespaces likely take the same codepath.
