This implementation generates lint errors because neither the `first`
nor `second` parameters are used, and that's generally
unexpected/incorrect for a `Comparator` implementation since it should
always consider both its parameters.

This change aims to prioritise tracks that have a 'smooth enough for
video' frame rate, without always selecting the track with the highest
frame rate.
In particular MP4 files extracted from motion photos sometimes have two
HEVC tracks, with the higher-res one having a very low frame rate (not
intended for use in video playback). Before this change
`DefaultTrackSelector` would pick the low-fps, high-res track.
This change adds a somewhat arbitrary 10fps threshold for "smooth video
playback", meaning any tracks above this threshold are selected in
preference to tracks below it. Within the tracks above the threshold
other attributes are used to select the preferred track. We deliberately
don't pick the highest-fps track (over pixel count and bitrate), because
most users would prefer to see a 30fps 4k track over a 60fps 720p track.
This change also includes a test MP4 file, extracted from the existing
`jpeg/pixel-motion-photo-2-hevc-tracks.jpg` file by logging
`mp4StartPosition` in
[`MotionPhotoDescription.getMotionPhotoMetadata`](b930b40a16/libraries/extractor/src/main/java/androidx/media3/extractor/jpeg/MotionPhotoDescription.java (L123))
and then using `dd`:
```
mp4StartPosition=2603594
$ dd if=jpeg/pixel-motion-photo-2-hevc-tracks.jpg \
of=mp4/pixel-motion-photo-2-hevc-tracks.mp4 \
bs=1 \
skip=2603594
```

This solution is in addition to the `JpegMotionPhotoExtractor` change
made specifically for these two-track motion photos in
5266c71b3a.
We will keep both changes, even though that change is not strictly
needed after this one, because adding the role flags helps to
communicate more clearly the intended usage of these tracks. This
change to consider FPS seems like a generally useful improvement to
`DefaultTrackSelector`, since it seems unlikely we would prefer a 5fps
video track over a 30fps one.

This new test is for `ExoPlayer.setVideoEffects()`. It plays the
one-second-long video, applies an overlay that prints the video frame timestamp
onto the frame, captures the output frame and compares the captured output
frame with golden.

These audio offload failure recovery tests model the DefaultAudioSink failing at audio track init and write operations in offload mode. Playback should recover and try again as DefaultAudioSink will disable offload mode.

Some devices supporting Performance Points for decoder coverage are missing coverage over the CDD requirements for H264. For these cases ExoPlayer should fall back to legacy resolution and frame rate support checks. If there is a stream evaluated as a PerformancePointCoverageResult of COVERAGE_RESULT_NO, then ExoPlayer checks for coverage of the 720p H264 CDD requirement.

Even when there's no display surface, MCVR can render frames to VFP, becuase by
the time the frame is processed:
- If there's still no surface, VFP will drop the frame;
- If there's surface, the processed frame would be rendered.
In short, placeholder surface is not needed in effect enabled playback. FWIW,
it is used to swallow frames directly from MediaCodec when there's no output
surface.

This change makes ExoPlayerImplInternal.releaseInternal() unblock the
app thread if a runtime exception is thrown while releasing components
from the playback thread.
Before this change, if a runtime exception occurred during releasing
components in the playback thread, ExoPlayer.release() would wait for
`releaseTimeoutMs` and then raise a player error. With this change,
the player error is reported only when the playback thread is blocked
but if there is a runtime exception, the application thread is
unblocked.
The impact of this change is potentially fewer ANRs on
ExoPlayer.release() at the expense of less error reporting.

We forgot to add it when we added AudioSink.release(). The commit
includes a test that ensures ForwardingAudioSink overrides all the
methods defined in the AudioSink interface.

If the reading period has already advanced and a track reselection procs that only affects the reading period media, then ExoPlayer may try and apply the reading period's track selection incorrectly unto the playing period. ExoPlayer should apply the playing period's track selection to the playing period instead.

If render error occurs due to AudioTrack initialization failure in offload mode, then ExoPlayer should allow retry as subsequent attempt will be with DefaultAudioSink disabling offload.

The `PreloadMediaPeriod.selectTracksForPreloading` can be called for multiple times at the preloading stage (before the period is being played). For example, when the period resumes preloading. This change fix the assertion failure in `ProgressiveMediaPeriod.selectTracks` caused by the wrong implementation of `PreloadMediaPeriod.selectTracksForPreloading` when it is trying to retain the previously preloaded streams.
Also the `TrackSelectorResult` parameter is changed to a list of `ExoTrackSelection`. We should compare the selections only rather than considering the `RendererConfiguration` in the `TrackSelectorResult` to decide whether to retain the streams, as for preloading case the renderers haven't consumed the samples yet.

Previously, the track format was used in VideoSampleExporter. Now, we use a
simulated decoder output format.

Also introduce a fluent API that allows callers to ignore non-fatal
errors (while avoiding adding boolean overloads for every method).
**Most** tests want to fail on non-fatal errors (since they likely
indicate user-visible issues like codec errors etc), only tests
explicitly testing fallback in error scenarios should want to ignore
them.
Before this change there were a few `playUntilXXX` methods. These can
now all be triggered via `play(player).untilXXX`, which means
effectively every 'until' condition is available in a 'play until'
variant that calls `play` just before waiting for the condition.

MediaCodec docs already allude to potentially mismatching H.264 level
between container and bitstream. Relax the initialization data check to
reflect this.

When applying edit lists, we need to output the last partial samples
to have all the necessary data needed for rendering.
The only case where we can omit the sample is for zero duration
audio data that has no additional information.
The current comment and variable name doesn't make this very clear
and this change improves the naming and the comment.
