Updating the list of supported codec in Mp4Muxer and
FragmenetdMp4Muxer is often missed when a new codec is added
in Boxes.java.

Add a new ByteBufferAllocator interface, with a simple
LinearByteBufferAllocator implementation that supports basic memory
allocations and reuse.
Add an AnnexBToAvccConverter.process override that takes a custom allocator

In all these cases I found at least one public method that takes or
returns a type from the dependency, or a type that inherits from a type
defined in the dependency.

When possible, make it the caller's responsibility to release the
GlObjectsProvider. It's good practice that the class creating an object
also releases it. It avoids releasing the same object (here, the
GlObjectsProvider) multiple times, which was causing
DefaultVideoCompositorPixelTest to fail.

This ensures that when the input sample rate handled by the encoder differs from the output of the AudioGraph, that output audio will not be broken.

The change includes adding a `MetricsReporter` interface with a default implementation to allow testing the `EditingMetricsCollector`.

The new asset loader is a wrapper around a provided `MediaProjection` and
`SurfaceAssetLoader`.
The test relies on automating the UI to get a `MediaProjection` instance, which
doesn't work reliably on all devices, so it's restricted to Pixel devices from
API 29 onwards.
For now only video is supported. The plan is to add support for audio playback
capture (also using `MediaProjection`) in a later change(s).

In a image sequence, seek to after the image duration should render the final
image frame. But currently it hangs as ConstantRateTimestampIterator doesn't
output any timestamp in this case

This test also changes the image seeking behavior to match ExoPlayer: now if
seeking to after the end of the image, the last frame of the image would still
be presented.

In the case of replace stream media item transition, it is important that dynamic scheduling does not set the next work task later than the transition boundary.

AV1 input buffers contain multiple compressed pictures.
Enable skipping only the last showable frame, while leaving
any reference pictures to be decoded later, as part of
the next decoder input buffer.
Partial skipping of AV1 input buffer is only applied when:
* fewer than 8 OBUs are delayed
* there's likely to be enough capacity in the decoder input buffer
for the next frame

Parsing AV1 bitstreams allows us to identify frames that are
not used as reference, and improve seeking or frame dropping
behavior.
The AV1 bitstream format is relatively quick to parse

From the `sampleMimeType`, we can know whether the media item contains video data, image data, and audio data. This is done for input media items, and the output media item.

- It's never used and handling multi-threading is costly.
- If the VideoCompositor and the VideoFrameProcessors use separate
threads and the same GlObjectsProvider, the GlObjectsProvider is
accessed from multiple threads. This class doesn't seem designed for
multi-threading.

When a timeline change occurs, the `AdTagLoader` will post an adLoad timeout task if currently waiting for an ad to load. Once sdk calls `loadAd`, any pending timeout tasks are removed. If the timeout occurs, the ad group is canceled and content will resume.
If the SDK proceeded to resume content without calling `loadAd`, then any pending timeout tasks should be removed or else a future ad group may error due to a previous timeout task.

Seeking will reset media periods following the current playing period. This includes resetting any current pre-warming media periods. Therefore while seeking, any current pre-warming should be disabled and reset.

When sample batching is disabled, copying of the ByteBuffer data
is not necessary as samples are written as they arrive.
Copying of the BufferInfo is necessary because the info is needed
for writing the moov atom.
The input ByteBuffer can be in little endian order, or have its
position set. AnnexBUtils now ensures big endian order before
inspecting bytes, and supports reading from a non-zero position.
This change reduces the amount of memory allocations by Mp4Muxer
in its default configuration
