Added UI and logic implementation for HDR mode and Resolution Height to be used as settings for both previewing and exporting.

-----
Context:
* Each sequence is wrapped as a single MediaSource, each being played
by an underlying ExoPlayer.
* Repeat mode is typically implemented in Players as a seek to the next
item in the playlist.
-----
This CL:
Repeat mode is triggered by listening for when the main input player
sees a play when ready change due to the end of the media item.
There is a slight delay at the end of the playback, before it repeats.
Setting repeat mode on the underlying players addresses this, but means
that the players will seek without waiting for the CompositionPlayer,
and as such previewAudioPipeline does not get the correct signals
around blocking/flushing.
PreviewAudioPipeline - The seek position can validly be C.TIME_UNSET,
however preview pipeline did not handle this case.
CompositionPlayer getContentPosition is given (through a lambda) as a
supplier to the State object, which means any comparisons between
previous/new state for this value does not work. In SimpleBasePlayer,
there is logic to use the positionDiscontinuityPositionUs for the
position change (see getPositionInfo called from
updateStateAndInformListeners), however this logic is not considered in
getMediaItemTransitionReason, so a condition needed to be added for
this case.
-----
Tests:
* Dump files clearly show the position and data is repeated.
* Assertions on the reasons for transitions or position
discontinuities.

The nullness checking is very verbose and redundant in some places, for
example, the ensures-non-null marking in the transformer activity, and it makes
changing features in the demo app more time consuming. The cost/benefit balance
seems to be in favor of removing this for demo code.
Note: the ExoPlayer main demo has nullness checks turned off.

This was previously only set on images because it was not ignored on
other media types. This parameter was made no-op for non-images in
7b2a1b4443.

For each item, AudioGraphInput now pads the input audio track with silence
to the duration given in onMediaItemChanged.
Possibly resolves Issue: androidx/media#921 .

This class is not ready for production app usage yet, so it is still
marked `@RestrictTo(LIBRARY_GROUP)` for now. Apps can experiment with it
in a non-prod context by suppressing the associated lint error.
