The static and dynamic metadata now build up in a list, such that when
the MediaMetadata is built, they are applied in an event order. This
means that newer/fresher values will overwrite older ones. The MediaItem
values are then applied at the end, as they take priority over any other.

The current API exposes an `ImmutableMap` of
`TrackGroup` -> `TrackSelectionOverride`.
This has several disadvantages:
- A difficult to use API for mutation
(`ImmutableMap.Builder` doesn't support key removal).
- There is no track selection specific methods,
how the generic map API mapps to the selection override is not complex
but to obvious for a casual reader.
- The internal data type is exposed, making internal refactor difficult.
This was done to have the API ready as quick as possible.
When transitioning the clients to the map API in <unknown commit>,
it became clear that the map API was too verbose and not mapping
to the clients needs, so utility methods
were added to make operations clearer and more concise.
Nevertheless, having to use utility method to use easily and correctly
an API is not the sign of a good API.
This cl refactors the track selection API for several improvements:
- Add a type `TrackSelectionParameters` that encapsulate the internal
data structure (map currently).
- For iteration, expose as a list.
- Add a `Builder` for easy mutable operations.
- Add track selection specific methods to avoid having utilities functions.
- Those operations are the same as `DefaultTrackSelector.Parameters`
for easier migration. (`setOverride` was renamed to `addOverride`)
- Move `TrackSelection` classes outside of `TrackSelectionParameters`
as their own top level classes.
The migration of the client code is straightforward as most of it
were already using the previously mentioned utility functions
that are now native methods.
The full migration has not been done yet, and is pending on this cl approval.

Issue: #9392 reports occasional IllegalStateExceptions from release()
in crashlytics,`with no way to reproduce locally. It seems likely there
is a bug somewhere in DRM handling, and ideally we would find that and
fix it.
However we haven't been able to find the problem, and in the meantime
these exceptions cause the entire app to crash. Although this is
arguably useful from a debugging perspective, it's obviously a poor
experience for developers and users, since all we're actually trying to
do is release the session, so maybe we shouldn't strictly care that it's
already released?
This change replaces the exception with an error log, which might be a
useful debugging hint if we see other DRM unexpected behaviour due to
references to released sessions being held for too long.

The new forcedSessionTrackTypes field was introduced in
<unknown commit>.
These usages are migrated in a follow-up change to add confidence that
the deprecated field continued to work correctly.

Common houses DataSource as an interface for reading data,
but most of the concrete implementations are in ExoPlayer.
This means that in practice, if an app wants to use a module
that reads using DataSource (e.g. extractor), they may be
forced to depend on ExoPlayer as well to get a concrete
implementation (e.g. FileDataSource). This change moves the
DataSource implementations into common to resolve this.

An upcoming change will modify ExoPlayer.Builder#build() to return
ExoPlayer, so any places that explicitly need a SimpleExoPlayer
instance should be using SimpleExoPlayer.Builder.

Update the UI module, the demos and most other users
to make use of the new player TracksInfo and track
selection override APIs.

Enable subtitle output in the PlaybackOutput and disable the text
renderer in the MkvPlaybackTest. Add WebvttPlaybackTest to test the
output of side-loaded WebVTT subtitles.

*** Original commit ***
Migrate callers of ExoPlayer.Builder#build() to buildExoPlayer()
An upcoming change will update build() to return Player.
PiperOrigin-RevId: 401468532
In a future change it will be updated to return ExoPlayer
We no longer need separate methods to build Player and ExoPlayer, so
buildExoPlayer will be removed shortly.

TracksInfo is very similar to
`MappingTrackSelector.MappedTracksInfo` with some
fields removed to simplify the Player API,
notably it doesn't expose the renderer concept.
A significant difference is the addition of a `selected` boolean
field which avoids having a separate `getCurrentTrackSelection`
API.
This cl is a part of the bigger track selection change,
splitted for ease of review.
In particular, the MediaSession implementation and UI usage
have been slitted in child cls.

This change makes asynchronous queueing non-experimental, it enables the
feature by default on devices with API level >= 31 (Android 12+) and
exposes APIs for apps to either fully opt-in or opt-out from the
feature.
The choice to use or not asynchronous queueing is moved out of
MediaCodecRenderer to a new MediaCodecAdapter factory, the
DefaultMediaCodecAdapterFactory. This is because, at the moment,
if an app passes a custom adapter factory to a MediaCodecRenderer and
then enables asynchronous queueing on it, the custom
adapter factory is not used but this is not visible to the user.
The default behavior of DefaultMediaCodecAdapterFactory is to create
asynchronous MediaCodec adapters for devices with API level >= 31
(Android 12+), and synchronous MediaCodec adapters on devices with older
API versions.
DefaultMediaCodecAdapterFactory exposes methods to force enable or force
disable the use of asynchronous adapters so that applications can enable
asynchronous queueing on devices with API versions before 31 (but not
before 23), or fully disable the feature. For applications that build
MediaCodecRenderers directly, they will need to create a
DefaultMediaCodecAdapterFactory and pass it to the renderer constructor.
For applications that rely on the DefaultRenderersFactory, additional
methods have been added on the DefaultRenderersFactory to control
enabling/disabling asynchronous queueing.

Removes subtitle allow-list by using SubtitleDecoderFactory.DEFAULT.
When the format is unsupported, the extractor registers one track and
sends the format with the Format#sampleMimeType set to TEXT_UNKNOWN and
Format#codecs field set to the actual subtitle MIME type.
The TextRenderer will recognize this MIME Type as not supported which is
gonna be visible in the event log.
