If ChannelMixingMatrix is public, this causes code to not build.

This is more future-proof because it is likely to simplify the upcoming
changes to the sample pipelines.

Also, allow isNoOp to default to false without the TODO, so that implementations
of isNoOp must opt-in to implementing the override in order to be considered for
skipping the effect (ex. for transcoding in Transformer).

Changes include:
1. Move the test file into muxer module
2. Code improvement
2. Remove dependency from Mp4Slicer library

Implement getMediaFormatInteger, a helper method simulating mediaformat.getInteger(name, defaultValue).

This reduces the API 29 restriction from MediaFormatUtil.getColorInfo to API 24, in
particular removing the method-based restriction to a constant-based restriction,
so that we can reduce usage of the API 29 class.

This also allows us to slightly simplify prior use-cases where we'd check
containsKey and getInteger to have a default value.

When clipping a MediaItem with start time > 0, the audio was ending
before the video. This is because:
- Audio timestamps are computed based on the sample sizes, with a start
  time set to streamOffsetUs (i.e. the streamStartPositionUs is not
  taken into account).
- The SamplePipeline was subtracting streamStartPositionUs from the
  timestamps before sending the samples to the muxer.
- As a result, the audio timestamps were shifted by
  streamStartPositionUs, while they should be shifter by streamOffsetUs.

* Account for `AssetLoader` output types.
* Consider cases that are not audio/video specific.
* Use `Format#sampleMimeType` for track specific conditions to check.
* Untangle `SamplePipeline` initilization from `AssetLoader` state.

- Add silent audio when the output contains an audio track but the
  current MediaItem doesn't have any audio.
- Add an audio track when generateSilentAudio is set to true.

Test cases for following boxes are added:

3. stss

Previously, this was limited to API 29. Expand this to all API versions.

Also, update the test to:
(1) skip based on SDR format input instead of HDR format input
(2) Check the exception message in order to disambiguate between the decoder tone
mapping error, and general video format support error.

Following changes are included:
1. Move test file into third_party/.../muxer/...
2. Rewrite tests for stts box and stsz box to use dump file infra instead of Mp4Slicer.
3. Remove existing test cases related to stts box which are kind of duplicate as it tries to cover the scenarios which are already covered by "DurationsVuForStts" related test cases.

Unstuck the muxer if the next timestamp in the track with the minimum
timestamp is larger than this minimum timestamp plus
MAX_TRACK_WRITE_AHEAD_US.

Using these annotations/checkers should hopefully make it marginally harder to use the wrong input values in the API.

When rendering frames at a rate higher than the screen refresh rate,
e.g. playing at 8x, the player is releasing multiple frames at the same
release time (nanos) which are then dropped by the platform. The output
buffers are available later and as a result MediaCodec cannot keep up
decoding fast enough.

This change skips releasing multiple video frames on the same vsync
period and proactivelly drops the frame. The frame is counted as skipped
rather than dropped to differentiate with frames dropped due to slow
decoding.

This call may cause performance overhead in some situations,
for example if the AudioTrack needs to query an offload DSP
for the current position. We don't need to check this multiple
times per doSomeWork iteration as the value is unlikely to
change in any meaningful way.

Before, if the upstream AssetLoader provides HDR to the VideoSamplePipeline when
HDR_MODE_EXPERIMENTAL_FORCE_INTERPRET_HDR_AS_SDR is requested, the
VideoSamplePipeline would attempt to tell the AssetLoader to output SDR, which
could be accomplished via MediaCodec tone-mapping in the AssetLoader.

However, this makes an assumption of the AssetLoader implementation, and
AssetLoaders may not all implement support for decoder tone-mapping. Remove javadoc
attempting to explain how AssetLoaders (ex. custom ones) could behave.

This method uses sampleRate, channelCount and pcmEncoding, so passing
AudioFormat is easier.

This will lead into a future change that builds the
encoderInputAudioFormat from encoder.getConfigurationFormat()

* FinalMatrixShaderProgramWrapper to FinalShaderProgramWrapper.

Rename ScaleToFitTransformation to ScaleAndRotateTransformation.

This better represents the operations that can be accomplished using this
effect. The name was originally named ScaleToFit* because it's not obvious how
to scale to fit using OpenGL, and this effect handled the scaling to fit in a way that no other MatrixTransformations did.

However, it's hard to discover how to rotate when skimming names of effects, so
it's probably more useful to convey that this effect rotates, than that it
scales to fit.

Format.toString unfortunately doesn't log colorInfo, and as Format holds a very
large set of values, it's unclear that it should. ColorInfo is useful for codec
exceptions though, so log this in ExportException.createForCodec.

Otherwise, a lack of HDR decoding support will result in the tests checking output files for HDR output, like HdrEditingTest.transform_noRequestedTranscode_hdr10File_transformsOrThrows, failing.
