ibaker 18d156fe3c Configure ProgressiveMediaSource with a Format for subtitles
This means we can complete preparation (and trigger track selection)
before opening a `DataSource`, which then means we only end up loading
the data for a selected subtitle track (instead of all tracks as
currently happens).

By making preparation trivial in this case (with no reasonable cause
of error), we can also remove the `suppressPrepareError` option added in
b3290eff10.

This change also fixes the implementation of
`ProgressiveMediaPeriod.maybeStartDeferredRetry` to only short-circuit
return `false` if the chosen track is not audio or video **and** there
is at least one audio or video track in this period.
