When trying to run the test on Android Studio, error "incompatible
types: Buffer cannot be converted to ByteBuffer" is logged. This is
because ByteBuffer.flip() returns a Buffer (and not a ByteBuffer).
Annotation @CovariantReturnType on ByteBuffer.flip() should resolve this
automatically but it doesn't seem supported at the moment.

Note that we simply use GlEffectsFrameProcessor in-app / GL tone-mapping, so PQ->SDR tone-mapping isn't yet implemented.
Tested manually using the demo on Pixel 7, to confirm that device and in-app tone
mapping behave similarly.

Adds the AudioMixerAlgorithm interface which allows for specialized
implementations of audio mixing that also efficiently convert between
source and mixing formats.
Initial implementation has two algorithms:
1. Float -> float (with channel mixing)
2. S16 -> float (with channel mixing)

To do that, rename PROGRESS_STATE_NO_TRANSFORMATION to
PROGRESS_STATE_NOT_STARTED and update Javadoc of ProgressState to not be
Transformer specific.

This should allow us to focus on HDR failures instead of network buffering
failures when debugging HDR issues.
These files are each used on several files, so it should be more worth the
test binary impact to move these files to local first.
Locally, tests did take less time after this diff

The MediaSourceFactory won't be used by the other AssetLoaders
In order to do that, ExoPlayerAssetLoader has been made public, and the
DefaultAssetLoaderFactory has become a wrapper around
ExoPlayerAssetLoader.

Otherwise, the decoders are not captured. It works at the moment for the
video decoder because decoding is still done on the sample pipeline but
it will moved to the AssetLoader soon.

`AudioProcessor`s expect direct buffers. This shouldn't make any functional difference in our code, but a custom audio processor might try to access the buffer from JNI in which case a direct byte buffer is more efficient.

`SilentAudioGenerator` could output a fractional audio frame, and this could cause downstream components to throw because of trying to read a complete audio frame but only seeing a partial one.
Calculate the output buffer size based on the frame size (which is a no-op for stereo 16-bit audio) and calculate a total number of frames to output then multiple by the frame size.

The duration in TransformerInternal.ComponentListener is set on the
Transformer internal thread, and is read on the playback thread. Making
this field volatile ensures that the playback thread reads the updated
value.

Rename ERROR_CODE_OUTPUT_FORMAT_UNSUPPORTED to
ERROR_CODE_ENCODING_FORMAT_UNSUPPORTED.
This makes the error code more consistent with ERROR_CODE_DECODING_FAILED on the
decoding side. Also, the error code is in the "Encoding errors (4xxx)" section,
so muxer errors probably should be in the "Muxer errors (7xxx)" section instead.
Additionally, no muxer errors currently seem to use
ERROR_CODE_OUTPUT_FORMAT_UNSUPPORTED, so this should be a safe change.

This is necessary to move video slow motion flattening to the
AssetLoader because this step can change the duration. As we use the
duration before flattening to calculate the progress, we must also use
the position before flattening.

Modify FrameProcessor and MatrixTextureProcessor interfaces to support
different input and output color transfers. Does not implement conversion between
color ranges (ex. HDR and SDR), but should allow for conversion between color
transfers of the same color range (ex. HLG and PQ).
This supports in-app tone mapping, where we need a single FrameProcessor to
input HDR color transfers (ex. HLG/PQ) and output SDR (ex. gamma2.2). This also
supports previewing, where we need a single FrameProcessor to be able to input HLG
and output PQ.
Manually tested by confirming colors still look right on SDR and HDR videos
with a rotation and color affect applied.

From this CL on, FrameProcessor listeners will be invoked from an Executor that
is passed in when creating the FrameProcessor.
GlTextureProcessor needs to invoke the ErrorListener on the said Executor too.

This is necessary to move video decoding to the AssetLoader. Otherwise,
if the decoder max pending frame count is reached, the AssetLoader will
stop queuing frames to the pipeline, and process data will not be called
anymore.

EncoderUtil using a static list to cache encoders means it's not possible to
use a different set of encoders for different tests when running all
robolectric tests together.

Bypass Z Fold 4 HDR10 tone-mapping bug by limiting the max frame count to 12.
This passed with a value of 14, and failed with a value of 15, but I figured I'd use 12 just to be safe.
