If the DFG ArrayMode says that an access is on an OriginalArray, then the checks should always enforce this

Previously, "original" arrays was just a hint that we could find the structure
of the array if we needed to even if the array profile didn't have it due to
polymorphism. Now, "original" arrays are a property that is actually checked:
if an array access has ArrayMode::arrayClass() == Array::OriginalArray, then we
can be sure that the code performing the access is dealing with not just a
JSArray, but a JSArray that has no named properties, no indexed accessors, and
the ArrayPrototype as its prototype. This will be useful for optimizations that
are being done as part of https://bugs.webkit.org/show_bug.cgi?id=101720.

Support list of tracks in caption media controls
https://bugs.webkit.org/show_bug.cgi?id=101669

Reviewed by Eric Carlson.

Attempt two of commit. The first time caused a build failure on Chromium.

Add some new elements to the media control shadow DOM that display the list of available
tracks on an audio/video element. The UI is hidden by default everywhere but on Mac,
where it is given a very basic design. At the moment only the list of available tracks
are displayed; The followup bug will make the UI active: https://bugs.webkit.org/show_bug.cgi?id=101670

No new tests - this doesn't expose any testable surface.
