Make the MediaCodecFactory injectable from the constructors of
MediaCodecAudioRenderer and MediaCodecVideoRenderer.

Before this we added the resource info to Truth assertions, but the
same info is missing if an exception bubbles out of the SUT.

When a listener is removed or released we may not have called
onEvents for events that happened before this point. To ensure
listeners don't miss events we need to trigger a final onEvents
with all events we have happened so far (if any).

In a later change, MediaCoderAdapter.Factory will be injectable to
MediaCodecRenderer.

Fix Matroska, Heif, FLAC, Ogg, Opus, Vorbis
extractor nullness check.

There should be no functional change.
Every media that fail to be parsed should still fail.
Every media that parsed successfully should still succeed.

This refactor aims to push all nullness constraints up the call stack to clarify each API nullness contract. This ensures implementation and caller have to prove their respective contract close to where such logic is implemented. This also allows to fail early if an nullness contract is broken instead of deep in the call stack.

For example, by adding a requirement that all implementation of `StreamReader.readHeaders` have to initialize `setupData.format` if the return false, each overriding method is forced to prove this next to the logic initializing it. This also means the runtime check might not be needed because the nullnessChecker can prove itself the contract holds.

This is in contrast with adding a null check at the point of usage, which will not catch logic errors where they are produce, but later when they are perceived; making it harder to debug and catching the issue at run time instead of compile time.

This will allow Player to move in common without
trackSelector and all its many dependency.

Currently all users of `getTrackSelector` are
downcasting it in `DefaultTrackSelector`, this change
thus does not break them.

Track selection API is intended to be reworked, methods
will be added to the currently empty interface.

Retrieve the capture frame rate and the SVC temporal layer count from
the smta box instead of the meta box because this is what Samsung do. It
is not guaranteed that the meta box will be present and will contain all
the necessary info in all slomo files.

Previously the helper would constantly lose (or never establish) sync
for non-1x playback speeds. This changes the helper to account for
other playback speeds correctly.

This was reported for SSA/ASS in PR #8265, but it seems to me the
SubRip part of the Matroska spec is similarly loose, so this change
handles null-terminated strings in both.

The old tag reflects the original name of this class. It was renamed in
2017:
<unknown commit>

Possibly the old name was kept for compatibility with existing logs
analysis? I didn't see an explicit discussion of this in the review
comments of the rename change.

The current tag confused me slightly - I assumed a line was being
emitted by the android.media.AudioTrack rather than ExoPlayer's
DefaultAudioSink.

This will mean the track is automatically used when running in a
playback test.

Command used to change the flag:
```
$ mkvpropedit sample_with_srt.mkv --edit track:3 --set flag-default=1

This is currently flaky, so it's better to disable it than end up with
flaky tests.

Migrate all classes that are simple to move to

The `AudioProcessor` interface requires that no more input is queued after
queueing end of stream, but `DefaultAudioSink` did queue more input and the
implementation of `SonicAudioProcessor` actually relied on this to drain output
at the end of the stream.

Fix this behavior by getting `Sonic` output in `getOutput` and having
`DefaultAudioSink` only queue input to processors that are not draining.

Also add TODOs to clean up audio processor implementations where the code
handles interaction that doesn't conform to the interface.
