austinried 25dafb0701 playback: show notification progress for unknown-length streams ...

Media3 marks a progressive stream live when the data source reports no
length and the extractor no duration, and a live item makes the media
session publish PLAYBACK_POSITION_UNKNOWN, so the notification progress
never advances even though the item carries the library duration.

The app only declares a stream length for a transcode of a track that has
one in a length-estimable format (`declaredStreamLength`), so a chunked
response stays live for an Opus/Ogg/Vorbis transcode (a length estimate
breaks the end-seek they rely on), for a transcode of a track whose
library duration is missing, and for a direct play the server does not
give a Content-Length. The now playing screen shows progress in all of
those because it falls back to the metadata duration; the notification
had nothing to advance.

Wrap the ExoPlayer in a ForwardingPlayer that reports an item with a
declared duration as finite. The session then publishes the real position
and the metadata duration, so the notification shows progress for every
unknown-length stream, not just Opus. The stream is still not seekable;
only the reported liveness changes.
