This adds the API surface for media button preferences in MediaSession
and MediaController. It closely mimics the existing custom layout
infrastructure (which it will replace eventually).
Compat logic:
- Session:
- When converting to platform custom actions, prefer to use
media button preferences if both are set.
- When connecting to an older Media3 controller, send the
media button preferences as custom layout instead.
- Controller:
- Maintain a single resolved media button preferences field.
- For Media3 controller receiving both values, prefer media
button preferences over custom layouts.
Missing functionality:
- The conversion from/to custom layout and platform custom actions
does not take the slot preferences into account yet.

Before this change:
* With legacy subtitle decoding (at render time), load errors (e.g. HTTP
404) would result playback completely failing, while parse errors
(e.g. invalid WebVTT data) would be silently ignored, so playback
would continue without subtitles.
* With new subtitle decoding (at extraction time), both load and parse
errors would result in playback completely failing.
This change means that now neither load nor parse errors in text or
metadata tracks stop playback from continuing. Instead the error'd track
is disabled until the end of the current period.
With new subtitle decoding, both load and parse errors happen during
loading/extraction, and so are emitted to the app via
`MediaSourceEventListener.onLoadError` and
`AnalyticsListener.onLoadError`. With legacy subtitle decoding, only
load errors are emitted via these listeners and parsing errors continue
to be silently ignored.

These events are always reported with the primary child period ID,
because this is the same ID used in the parent `MergingMediaSource`'s
Timeline.
This ensures that e.g. loading errors from sideloaded subtitles (which
uses `MergingMediaSource`) are now reported via
`AnalyticsListener.onLoadError`.
It results in non-error events being reported from these children too,
which will result in more `onLoadStarted` and `onLoadCompleted` events
being reported (one for each child).

Use this for sideloaded subtitles, so preparation can still complete
despite an error from e.g. `DataSource.open`. In this case, no subtitle
tracks will be emitted.

This is prework for implementing
`RandomParameterizedSpeedChangingAudioProcessorTest`, which depends on
Sonic's resampling algorithm's behaviour.
This is a non-functional refactor.

When a `SampleQueue` is prepared prior to playback, the start position may be less than the timestamp of the first sample in the queue and still be valid. This scenario can come about with specific clipping values and if all samples are sync samples. Currently, with `ClippingMediaPeriods` around `ProgressiveMediaPeriods`, if the `SampleQueue` has already been reset through the seekTo operation in `onPrepared`, then in the aforementioned scenario the seekTo operation in `handleDiscontinuity` will remove all samples and reset the loading periods unnecessarily.
The solution is that if the `ProgressiveMediaPeriod` has already handled a seekTo operation for the same position and the sample queue has not been read yet, then loading does not need to be reset.
The tests in `MergingPlaylistPlaybackTest` were specifically causing this behavior through its setup of `MergingMediaSources` around clipped `FilteringMediaSources`. Since the video content was not 'all sync samples', there would always be a discontinuity to handle and the audio content being 'all sync samples' would start with samples post start time.
These changes also remove the flakiness from the `MergingPlaylistPlaybackTest`.

Currently every test in the library passes `null` here, which seems to
end up being passed into non-null places in the library. This change
removes the parameter and instead initializes the field to a
`DefaultAllocator` instance in the same way that `DefaultLoadControl`
creates one.

This ensures that the buffers are correctly marked as `rendered = true`
(and therefore `renderered = false` is meaningful when it's present).

This allows users to extend and customize specific methods of the `TrackOutput` implementation while inheriting default behaviors for others.

Childrens returned by the legacy service when a Media3
browser connects are cached and returned with the first
`getChildren` call in case the same `paranetid` is
requested.
In any other case the cache is immediately cleared.

Updated logic to walk forward in the timestamps array to include all frames within the valid edit duration, accounting for out-of-order frames. This ensures that no frames with timestamps less than `editMediaTime` + `editDuration` are incorrectly excluded.

When receiving an error from a legacy `MediaBrowserService` after
having successfully subscribed to a given `parentId`, the callback
needs to be asked to load the children again to receive an error
from the service.
Before this change such an error was dropped as a no-op by Media3
without the `MediaBrowser` giving a chance to react on such an error
being sent by the legacy service.

The `CapturingRenderersFactory` is only needed if the output is
asserted on, e.g. by using `PlaybackOutput` and
`DumpFileAsserts.assertOutput()`.

`HlsExtractorFactory` instances are mutable, so storing one in a static
field is not safe, and can lead to state accidentally/surprisingly being
shared between different player instances.

This ensures these values are still updated even if the delegate
`DataSource.open()` throws an exception (e.g. an HTTP 404).

The `DefaultLoadControl` implementation of onTracksSelected only utilizes the `Renderer[]` parameter for use in stream type, of which it can collect from the `ExoTrackSelection[]` parameter.

Added UI and logic implementation for the following export settings:
* Output audio MIME type
* Output video MIME type
* Enable debug tracing
* Use Media3 Muxer
* Produce fragmented MP4
The settings are shown in a dialog when `Export` button is clicked.

For simplicity, the following SDK checks when adding supported video codecs were removed from Transformer demo.
1. Adding H265 for API >= 24.
2. Adding AV1 for API >= 34.
