-----------
[HTML Tracks] Add more tests for untested areas of the HTML TextTrack
specification
rdar://180313782
https://bugs.webkit.org/show_bug.cgi?id=317594
Reviewed by Eric Carlson.
Add a second batch of tests covering previously untested TextTrack
behaviors: cue lifecycle during playback (time marches on with
seeking and mid-stream cue mutations), TextTrackCue event handlers
and endTime setter semantics, cue edge cases (unbounded endTime and
negative-time cues), and in-band TextTrack exposure rules
(IDL accessor presence, empty dispatch type for non-metadata kinds,
in-band tracks not blocking readyState). The in-band test uses
synthetic CEA-608 captions via mp4-generator.js / caption-generator.js
to avoid an external asset dependency.
text-track-cue-events-and-handlers.html's "endTime setter: shrinking
past currentTime fires 'exit'" subtest fails because WebKit clears
activeCues but does not fire 'exit'; the failure is tracked by
rdar://180298688 and recorded inline in the test's expected.txt.
