The join mode is used for two cases: surface switching and mid-playback
enabling of video.
In both cases, we want to pretend to be ready despite not having rendered
a new "first frame". So far, we also avoided force-rendering the first
frame immediately because it causes a stuttering effect for the
mid-playback enable case. The surface switch case doesn't have this
stuttering issue as the same codec is used without interruption. Not
force-rendering the frame immediately causes the first-frame rendered
callback to arrive too early though, which may lead to cases where
apps hide shutter views too quickly.
This problem can be solved by only avoiding the force-render for the
mid-playback enabling case, but not for the surface switching case.

Also explicitly use a synchronized list to collect cues. The previous
bare `ArrayList` was probably fine, because the `ConditionVariable`
creates a memory barrier between the main thread and the test thread,
but this seems more explicit (and any performance implications of the
synchronization don't matter for this test).

The workaround check is now part of CTS and we should be able
to rely on the PerformancePoints values (or at least can be sure
that they cover all CDD requirements)

Some media can read color info values from the bitstream
and may partially set some of the SDR default values in
Format.ColorInfo. Setting these default values for SDR can
confuse some codecs and may also prevent adaptive ABR
switches if not all ColorInfo values are set in exactly the
same way.
We can avoid any influence of HDR color info handling by
disabling setting the color info MediaFormat keys for SDR
video and also avoid codec reset at format changes if both
formats are SDR with slightly different ColorInfo settings.
To identify "SDR" ColorInfo instances, we need to do some
fuzzy matching as many of the default values are assumed to
match the SDR profile even if not set.

Add a new method `onUsedByPlayer(PreloadMediaSource)` for `PreloadMediaSource.PreloadControl`, which will be invoked when the player starts to use the `PreloadMediaSource`, or calling `PreloadMediaSource.preload` while the player is already using that source. `DefaultPreloadManager` will immediately preload the next source when receiving `onUsedByPlayer` event.

Confirmed that the HLG extension displays properly on Pixel 7 Pro, API 34 and Samsung S24, API 34. On these devices, this fixes the washed out HLG preview issue on API 34, where the PQ ext had a washed out look, and where the HLG ext is supported (this bug didn't occur on API 33, only 34).
More info on manual tests done to sanity-check:
* Test cases: Transformer debug SurfaceView and ExoPlayer.setVideoEffects
* Test inputs: HLG and PQ
* Test devices: Pixel 7 Pro (API 33 & 34), Samsung Galaxy S24 (API 34)
* Added debugging: Logging colorInfo used in GlUtil.createEglSurface
No regressions were seen. HLG extension is used more in API 34, and behavior stays the same on API 33. Only human-visible change without logging is that HLG content looks better on API 34, for Samsung S24 and Pixel 7 Pro.

Renderers may be enabled for subsequent media items as soon as the current media item's renderer's isEnded() returns true. Currently, when a player is set to pause, it stops all renderers that are `STATE_STARTED`. When a player is set to play, it starts all renderers that are enabled. This would include renderers that were enabled early for the subsequent media item. The solution is to only start renderers that are enabled by the current playing period.

Some devices just don't work very well with the synchronous
model, but are currently still excluded from our approximate
API 31 check. This change allows to include additional devices
or device groups by passing in the Context to the default
adapter.
It also adopts the workaround added in ebceee08c6
for Fire TV Smart devices that exhibit this issue.

Also remove intermediate object allocations in
`Util.toByteArray(int...)`.
`Util.toByteArray(InputStream)` is kept (but deprecated) because it's
been part of the library for a while and might be in use by some apps.
The others are much newer, so the chance of usages outside the library
is very low, so we just remove them directly.

Renderers may be enabled for subsequent media items as soon as the current media item's renderer's isEnded() returns true. When a renderer is being enabled and the player is 'playing', that renderer is also started. When playing a mixed playlist of images and content with audio & video, the player may skip some image items because the early-starting of the audio renderer causes a clock update.
A solution is to only start the "early-enabled" renderers at the point of media transition and add a condition on DefaultMediaClock to use the standalone clock when reading-ahead and the renderer clock source is not in a started state.

The old methods are deprecated and are called from the new

`BasePreloadManager` coordinates the preloading for multiple sources based on the priorities defined by their `rankingData`. Customization is possible by extending this class. Apps will implement `TargetPreloadStatusControl` to return preload manager the target preload status for a given `rankingData` of the source.
`DefaultPreloadManager` extends from the above base class and uses `PreloadMediaSource` to preload media samples of the sources into memory. It also uses an integer `rankingData` that indicates the index of an item on the UI, and the priority of the items is determined by their adjacency to the current playing item. Apps can set the index of current playing item via `DefaultPreloadManager.setCurrentPlayingIndex` when the user swiping is detected.

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.

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.
