Expand on the sourcing of multitrack audio and video track attribute values for
the id, kind, label and language attributes according to feedback provided by
the Inband (Text) Tracks CG.

See a proposed patch at
which should be applied to the AudioTrackList and VideoTrackList section:


The current spec is incomplete for how to fill the attribute values of (inband)
audio and video tracks when parsing from a media file for the different file
formats that are typically supported by UAs.

Currently, it is only specified by example how .kind values are provided
(there's a typo in the table title, btw, which should be .kind and not .kind()

The suggested changes are:

* the .id, .label and .language attributes (audioTrack.id and videoTrack.id
etc) are sourced identically to how an inband textTrack.id etc. attribute is
sourced (as described in https://github.com/w3c/html/commit
/5fbd9199cc711d8ae9155da58be3d4368272e00d and bug #25132)

* the .kind attribute table is expanded to be complete for Ogg, WebM, MPEG-2,
MPEG-4 and DASH file formats

The same specifications as in bug #25132 were used to clarify and complete the
information that was prepared by the Inband Text Track CG in their wiki:

The CG has reviewed and ok-ed the draft patch as prepared in bug #24986.
I'm looking to have the patch adjusted and applied in a manner that suits the
WHATWG style.
