This CL aims to separate Fragmented MP4 related logic in a separate public class.
Earlier all the logic was in a single class `Mp4Muxer`.

This property is transformer specific and does not belong to
muxer interface.
This is to eventually replace muxer interface in Transformer module with
muxer interface in Muxer module.
PiperOrigin-RevId: 618895836
The immediate plan is to replace `Transformer Muxer interface`
with this one.
It was not straight forward to move/change `Transformer Muxer interface`
hence this intermediate step.
The follow up CL will also remove fragmented MP4 related code from
`Mp4Muxer` and move it into `FragmentedMp4Muxer implements Muxer`.

This is the most widely-used test-skipping method I'm aware of, so I figured this
would be a great method to scale usage of AssumptionViolatedException.

Issue: androidx/media#725
Ideally the test to transmux a `ts` file (having 3 bytes NAL start code)
should go into `Mp4MuxerEndToEndTest`but `Mp4MuxerEndToEndTest` uses `MediaExtractor` and `MediaExtractor` is returning samples with `4 byte NAL start code` which will not exercise the newly added code path.
Hence the test is added in `TransformerWithInAppMuxerEndToEndTest` which
internally uses `media3 extractor` and feeds samples with `3 bytes NAL start code`
only.

Seeking will consist of the following steps:
- Block the AudioGraph input data.
- Flush the AudioGraph.
- Seek the ExoPlayers.
- Unblock the AudioGraph input data.

This also makes it more consistent with newer testId tests that don't have nullness, so tests don't look inconsistent, and was pretty easy to do :P

This was broken by 2fa38d15dd, which added an assumes
method, but missed the `!` operator for the tests where HDR is
unsupported. Add an assumes method that assumes a lack of support
for HDR.
Tested on the failing device (Pixel 7) and confirmed this fixes
the test on that device, to throw AssumptionViolatedException
instead of allowing test logic to run after failing the
assumption.

When flushing the AudioGraph, the AudioMixer will be preserved but the
sources will be recreated. This is probably a bit less efficient but
makes the logic simpler. Indeed, if we had to keep the sources alive,
we would need to add a way to reconfigure them with a new timestamp for
seeking. We would also need to change the way sources are ended because
they are currently removed when they are ended. Also, it is acceptable
to have a small delay when seeking, which means that performance is less
critical than for playback.

getSupportedEncoderNamesForHdrEditing became getSupportedEncodersForHdrEditing at some point, but this comment wasn't updated before...

Pass firstAssetLoaderOutputFormat to videoSampleExporter for non-video use cases, so that the downstream components like the videoFrameProcessor can be set up with the right output color. Surface creation is still in the VSP so can't do this for all use cases currently.
also moves getDecoderOutputColor() to TransformerUtil, since it is used in multiple places and doesn't make sense for once to have reference to the other.

Plumbing hdrMode through the default asset loader factory via the constructor is problematic because it breaks API boundaries. It means there is another way to set hdrMode outside of Composition.java and TransformationRequest.java, which is error prone and cause problems if someone an app starts customizing the assetloaderfactory. It also means custom asset loaders can't receive this information without hacking around.
The introduction of the composition-level settings class makes this approach easily extensible for other settings applied on the composition level but use in an individual asset level basis (e.g. ultraHDR support).

Add abilitiy to use real surfaces in instrumentation tests
using the ActivityScenarioRule and an activity class for testing
purposes.

This new test is for `ExoPlayer.setVideoEffects()`. It plays the
one-second-long video, applies an overlay that prints the video frame timestamp
onto the frame, captures the output frame and compares the captured output
frame with golden.

Previously, the track format was used in VideoSampleExporter. Now, we use a
simulated decoder output format.
As the last expected change for this bug, also adds release notes

MediaCodec docs already allude to potentially mismatching H.264 level
between container and bitstream. Relax the initialization data check to
reflect this.
