Simplifying and clarifying variables, and adding comments.

Tested by confirming demo-gl and demo-transformer both
correctly display videos

This value is the default used by widevine_test at
proxy.uat.widevine.com, but it's not easy to find that info so it's
clearer to document it explicitly here for consistency with the "policy
tests" section below where all the URLs contain a video_id parameter.

This string is case-sensitive.

The existing wording would be correct if prefixed with
"Returns false if [...]", but it seems confusing to a document a boolean
method in terms the condition it returns false - so I reworded it in
terms of when it returns true.

After this change exceptions throw by MediaCodec during
encoding/decoding will result in TransformationExceptions with
ERROR_CODE_ENCODING_FAILED/ERROR_CODE_DECODING_FAILED.
Before this change ERROR_CODE_FAILED_RUNTIME_CHECK was used.

Expected images are taken on emulators, so a larger acceptable
difference from expected images must be accepted on physical devices.

Live speed adjustment is used for all live playback at the moment,
but has no user visible effect if the media is not played with low
latency. To avoid unnecessary adjustment during playback without
benefit, this change restricts the live speed adjustment to cases
where either the user requested a speed value in the MediaItem or the
media specifically defined a low-latency stream.

This ensures we test the API level specific logic, in particular
around 5G-NSA detection.

Robolectric has a remaining bug that it doesn't support listening
to service state changes. Hence, we need to ignore some tests on
these API levels still until this is fixed.

Multiple listeners can be added to Transformer and its builder.
All or specific listeners can also be removed.

Codec and its factories can use MediaCodec directly as for API >= 21,
the SynchronousMediaCodecAdapter methods used in Codec just correspond
to a single MediaCodec call each so there is no reason to have another
wrapping layer.

Exceptions thrown by MediaMuxer are converted MuxerExceptions
and later to TransformationExceptions with ERROR_CODE_MUXING_FAILED.

We [recommend apps use Cronet](https://exoplayer.dev/network-stacks.html#choosing-a-network-stack)
and the demo app uses it, so we should make it easy to look-up errors
like this in our troubleshooting page.

The media codec renderers have fallback logic in getDecoderInfos
to assume that E-AC3 decoders can handle the 2D version of E-AC3-JOC and
that H264/H265 decoders can handle some base layer of Dolby Vision
content. Both fallbacks are useful if there is no decoder for the
enhanced Dolby formats.

Both fallbacks are not applied during track selection at the moment
because the separate MediaCodecInfo.isCodecSupported method verifies
that the mime type corresponding to format.codecs is the same as the
decoder mime type (which isn't true for the fallback case).

To fix the fallback logic, we can just completely remove this additional
check because it's not needed in the context of this method that is only
called after we already established that the decoder can handle the
format.sampleMimeType.

In addition, we need to map the Dolby Vision profiles to the equivalent
H264/H265 profile to make the codec profile comparison sensible again.

SampleQueues may be released in the context of a finally block
after an out of memory error. Allocating in that scenario can
throw yet a new OutOfMemoryError. By safely releasing SampleQueue
memory, we increase the possibility of handling the error
gracefully.

This method has been deprecated since 2.12.0 ([commit](https://github.com/google/ExoPlayer/commit/d1bbd3507a818e14be965c300938f9d51f8b7836)).

Also remove
DashMediaSource.Factory#setLivePresentationDelayMs(long, boolean), this
method has been deprecated since 2.13.0 ([commit](https://github.com/google/ExoPlayer/commit/41b58d503ae6666cea4ded114afde9fb23a5e199)).

This class is already called StyledPlayerControlViewLayoutManager, it
seems unecessary to repeate the 'styled' word again in this context.

These were missed in https://github.com/google/ExoPlayer/commit/46ab94bd4152b0addc2253585435186fc9e75582

These references will be re-written to PlayerView when exporting to
exoplayer2, so this commit results in some small reformatting changes.

Also fix a reference to LegacyPlayerControlView that should be
StyledPlayerControlView.

The draw method was disabling vertex attrib arrays but not re-enabling them. Remove the call to disable the vertex attrib arrays so that then remain enabled after the program is created.

Manually verified by setting the surface type to spherical in the demo app and playing a spherical sample video.

The encoder and sonic are now set up in the constructor rather
than in a configuration method called from processData(). This
is more similar to VideoSamplePipeline and reduces null checks.

When sending a MediaItem to a MediaSession with a Media3 MediaController important information is removed for privacy reason. To look up the fully populated MediaItem the mediaId is used as a key. Hence having the mediaId marhalled to the JSON representation that is sent to a Cast device enables app developers to use the same look up facilities.

Only allowing TransformationExceptions to be created using the factory methods helps keeping error messages consistent. This is consistent with ExoPlaybackException.

The UI component will be switched over to use them in a
subsequent commit, once the translations have been
imported.
