PQ and HLG have different luminance ranges (max 10k nits and max 1k nits resp). In GL, colors work in a normalised 0 to 1 scale, so for PQ content, 1=10k nits and and for HLG content, 1=1k nits.
This cl scales and normalises PQ content appropriately so that all HDR content works in the HLG luminance range. This fixes two things
1. Conversions between HLG and PQ are "fixed" (before the output colors looked too bright or too dark depending on which way you are converting)
2. color-altering effects will be able to work consistently across HLG and PQ content
1 is tested in this cl. 2 will be tested when ultra HDR overlays are implemented, both cases have been manually tested to ensure the output looks correct on a screen.

This change avoids a muxer deadlock when:
1. Sequence of items
2. First item has audio track that is shorter than video
3. Audio finishes, and muxer refuses to write more than 500ms of video
consecutively.
SequenceAssetLoader fails to progress to the second item. A muxer
deadlock is possible when the audio of the first item finishes,
audio end-of-stream is not propagated through AudioGraph, and muxer blocks
video, preventing SequenceAssetLoader to move to the next item in sequence.
By triggering silence generation early as soon as audio EOS is
encountered, we ensure SequenceAssetLoader can progress to the next item.

After this CL, DVFP waits for flushing until all frames registered previously
arrives.
Previously, ETM records the difference between the number of registered frames,
and the number of frames arrivd on the SurfaceTexture, when flushing. (Note
that ETM is flushed the last in the chain, as flushing is done backwards from
FinalShaderProgramWrapper). ETM then waits until the number of frames arrive
after flush.
The normal flow is, MediaCodecVideoRenderer (MCVR) registers a new decoded
frame, in `processOutputBuffer()` to DVFP, MCVR call `codec.releaseOutputBuffer()`
to have MediaCodec render the frame, and then the frame arrives in DVFP's ETM.
However there might be a discrepancy. When registering the frame, ETM records
the frame on the calling thread, ~instantly. Later when the rendered frame
arrive, ETM records a frame is available on the task executor thread (or
commonly known as the GL thread). More specifically, when a frame arrives
in `onFrameAvailableListener`, ETM posts all subsequent processing to
the task executor. When seeking, the task executor is flushed as the first
step. It might be a frame that has already arrived on ETM, and the processing
of such frame has already been queued into the task executor; only to be
flushed as a result of flushing the task executor. If this happens, the frame
is considered to be never have arrived. This causes a freeze on the app,
because ETM'll wait until this frame arrives to declare flushing has completed.

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.

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).

* @Before and @After usage. [1].

@Before method should typically be paired with an @After method,

the test does.
In tests, inlining final class variables is preferrable [1]. In general
things like the file path should be part of the test (the @Rule means
we don't need before/after) if only used once.
Statically importing values and using them directly is preferable to
having a variable declared as non-final that's effectively final,
because from a readability perspective someone can see (the caps) that
the value is final static and immutable, so doesn't have to check if
it's changed/reassigned.

buffers was limited to avoid using more and more memory if producer (asset
loader) gets far ahead of the consumer (exporter).
Previously this limit was fixed at 10 buffers, but increasing the number of
buffers can make some transmux operations much faster. Allow allocating between
a min and max number of buffers, and also set a target allocation size beyond
which new buffers can't be allocated. This allows audio formats which require
many small buffers to be processed more quickly, while preventing allocating
too much memory for hypothetical very high bitrate formats.
'Remove video' edits on local videos in particular get much faster, because
audio buffers are very short and there are lots of them. With a sample 10
minute video, a 'remove video' edit took 2 seconds (36 seconds before this
change). With a sample 1 minute removing video took 0.25 seconds after this
change (2.5 seconds before).
The speed improvement is smaller for other types of edits that retain the video
track. Transmuxing a 10 minute video retaining the video track took 26 seconds
(40 seconds before).

MIME types are case-insensitive, but none of the many existing
comparisons across our code base take this into account. The
code can be made more robust by normalizing all MIME types at the
moment they are first set into a class/builder and adding toLowerCase
as part of the normalization.
Most concretely, this fixes an issue with playing HLS streams via
the IMA SDK where the stream MIME type is indicated with all lower
case "application/x-mpegurl", which failed the MIME type comparison
in DefaultMediaSourceFactory.

Skip wearable devices, which don't have the same CDD requirements on codecs from Android 5 (API 21).
Limit an existing skipping case to pre API 33 devices, so that we can catch failures on Android 13 (API 33) onwards, and add OnePlus 9 Pro which also times out calculating SSIM. Remove TODOs for removing test/SSIM skipping now they are restricted to API version.

This device over-reports encoding capabilities, so skip the test.
This is a Pixel device that was upgraded to Android 12 (API 31/32) so the issue should only affect devices that didn't take OTAs.

The dump file diff as part of this change is because using AudioGraph
means the 2nd item is automatically edited to match the AudioFormat of
the 1st item {44.1KHz mono}, rather than {48KHz stereo}.
Manually verified that for the 2nd item, data output:
* Before: 66936 bytes (16734 frames) output = 348_625us of audio.
* After: 30750 bytes (15375 frames) output = 348_639us of audio.
The small final buffer is caused by SonicAudioProcessor outputting all
pending data when EOS queued, and is WAI.

When transmuxing, we usually only need to offset the timestamp by the position of a mediaItem in a sequence.
Trim optimization introduces another type of offset: for the transmux of the second part of the video we need to offset the timestamps by the total duration already trancoded by transformer.

Move remote 8K file to local and trim to 320ms.
Trim done with ffmpeg:
`ffmpeg -i {remote_file} -t 0.3 -c:v copy -c:a copy 8k24fps_300ms.mp4`
