This involves promoting `setTextTranscodingEnabled` to
`ExtractorsFactory`, and also making it experimental, to indicate it's a
short-lived method.

Mp4Extractor will no longer be wrapped in SubtitleTranscodingExtractor, but instead use SubtitleTranscodingExtractorOutput under the hood.
FLAG_EMIT_RAW_SUBTITLE_DATA flag will be used to toggle between subtitle parsing during extraction (before the sample queue) or during decoding (after the sample queue).

The capabilities change depending on the attributes, so we should
pass down the actual attributes used during playback and update
the capabilities whenever these change.

This means in a later change we can still use some of the info for CBR
files, even if we want to ignore the imprecise table of contents and
seek based on a constant bitrate assumption instead.

An audio file can only play sound between two PCM samples (the 'start'
and 'end' of section of a wave form). Therefore when calculating
duration from a count of PCM samples we need to subtract one first (the
'end' sample which has no duration of its own).
This only changes durations by one PCM sample (21us - 22us for 44.1kHz sample
rate).

The extractor knows the PCM encoding of the losslessly
encoded data in the samples and should set it in the
Format to allow downstream components to use this information.

We introduce SubtitleParser.Factory that supports no formats to be used FragmentedMp4Extractors that will not do any subtitle parsing on the extraction side. We also slowly move away from using SubtitleTranscodingExtractor to SubtitleTranscodingExtractorOutput (hence making it public).
This is required by individual Extractor impls so that they can start using SubtitleTranscodingExtractorOutput rather than be wrapped by SubtitleTranscodingExtractor. The latter is to be deprecated after all the subtitle related Extractors have achieved this migration.

Whenever the inputColorInfo updates, update the samplingGlShaderProgram.
Also, allow either SDR or gamma2.2 to be used for HDR->SDR tone-mapping
`outputColorInfo` request. This is required because we can't update the
`outputColorInfo`, but plan to always use gamma2.2 for `outputColorInfo` in the
future.
This allows VideoFrameProcessor to work as is for exoplayer previewing, but
only when not seeking. As we haven't plumbed the per-stream inputColorInfo from
ExoPlayer down to VFP.registerInputStream, follow-up CLs will be needed to
properly support previewing with changing inputColorInfo.

This behavior was previously available as opt-in via
`MediaItem.DrmConfiguration.Builder.setPlayClearContentWithoutKey` and
`DefaultDrmSessionManager.Builder.setPlayClearSamplesWithoutKeys`. This
change flips the default of both these properties to true.
This should speed up the time for playback to start when playing DRM
content with a 'clear lead' of unencrypted samples at the start.
Previously playback would wait until the keys for the later encrypted
samples were ready. The new behaviour could result in mid-playback
stalls/rebuffers if the keys are not ready yet by the transition from
clear to encrypted samples, but this is not really a regression since
previously playback wouldn't have started at all at this point.

This file is CBR encoded with LAME, so it has an `Info` header (the CBR
equivalent to `Xing`).
A follow-up change will use this file in `Mp3ExtractorTest`.

These methods sound similar, but have different behaviour. This change
tries to make the distinction clearer, and sign-post from one to the
other.

When the media notification controller is requested for a session
with `getConnectedControllerForSession` and the `Future` is not null
but not yet completed, the `Future` was returned either way. This was
reported as creating a race condition between the notification
being requested for update the very first time, and the media
notification controller having completed connecting to the session.
Returning null from `getConnectedControllerForSession` when the
`Future` is available but not yet done fixes the problem. This is
safe because for the case when a notification update is dropped,
the media notification controller will trigger the update as soon
as the connection completes.

`Cea608Parser` and `Cea708Parser` don't currently work correctly on
their own without the re-ordering of input buffers implemented in
`CeaDecoder`, and it's not clear how we can properly do this re-ordering
during extraction. This change ensures that if 'parse subtitles
during extraction' is enabled, CEA-6/708 subs will be passed through
without transcoding and can then be decoded during rendering by
`Cea6/708Decoder`.

Invalid frames have no impact on ExoPlayer ability to play the media and should not fail on errors.
Some tools can add 100Mb images in the tags that will trigger recoverable OOM with this fix.
The `PlaybackService` of the demo app is declared
as `androidx.media3.session.MediaSessionService` instead
of `androidx.media3.session.MediaLibraryService`. While
this technically works, its confusing to do that in the
demo app.
Generally, apps that declare the legacy
`android.media.browse.MediaBrowserService` should also
declare `androidx.media3.session.MediaLibraryService`
and the demo app should reflect this common case.

The `Cea608DecoderTest` added here fails if re-ordering is removed from
`CeaDecoder`.
The `Cea608ParserTest` is added with `@Ignore` because there's currently
no re-ordering support in this part of the subtitle handling pipeline
(partly because there's no concept of 'current playback time', meaning
it's hard to know **when** to re-order).

When the 'when' timer of the notification is disabled
`DefaultMediaNotificationProvider` may set `C.TIME_UNSET`
as the time. Users reported problems on some devices with
this and the docs ask for an event time that probably
shouldn't be a negative number.
This change sets `0L` instead of `C.TIME_UNSET` when the
timer is disabled.

Changes includes;
1. Public API to enable fMP4 and to pass fragment duration.
2. Added `FragmentedMp4Writer`.
3. Added logic to create fragments based on given fragment duration.
4. Write "moov" box only once in the beginning.
3. Add all the required boxes for current implementation.
4. Unit tests for all the new boxes.
5. E2E test for generating fMP4.
Note: The output file is un seek-able with this first implementation.

Mp4Muxer does not support out of order B-frames. Currently it
silently writes out of order B-frames, producing an invalid file (with
negative sample durations).
Although `Mp4Extractor` is somehow able to process this invalid file and
`Exoplayer` is able to play it but that is unexpected.
The `sample.mp4` test file contains B frames. Other test files does not
contain `H264 video + AAC audio` format hence created a new test file by
running `sample.mp4` via `Transformer` after applying some effects.

This more closely matches the intended, documented behaviour of this
method. The previous implementation was incorrectly checking
`sampleDataEnd + newSampleSize`, but it's more correct to compare
`existingSampleDataLength + newSampleSize`, in order to handle the
case of non-zero `sampleDataStart`. We've already checked above whether
`newSampleSize` fits after `sampleDataEnd` without growing or
reshuffling the array, so no need to basically repeat that check.
In the case of handling one sample at a time, the previous
implementation resulted in `sampleData` growing by `sampleSize`
**every time** the pointers reached the end. With the new check for
`sampleDataStart == sampleDataEnd`, this is avoided by always writing
each new sample at the start of the array (because the previous sample
has already been consumed), meaning `sampleData` remains equal to
`sampleSize` without growing.
