- For single-asset, the behavior stays the same. Transcode if and only
if it's necessary,
- For constrained multi-asset, always transcode, except if the setter to
transmux is set. This is to avoid failing if a MediaItem that doesn't
require transcoding is followed by a MediaItem that does require
transcoding.

ParcelFileDescriptor is quite specific and removing it allows to have
less overloads of startTransformation.
A follow-up CL will undeprecate the overload that takes a MediaItem.

Also add a Builder to EditedMediaItem to avoid having a constructor with
many optional parameters, or a chain of constructors.

Transformer convention has been to avoid splitting into packages unless
necessary.
See https://jlbp.dev/JLBP-2: "Prefer fewer packages over more packages
to avoid unnecessarily publicizing internal details, since any
dependency across package boundaries needs to be public.

Also remove usages of TransformationRequest convenience methods
(setScale, setRotationDegrees and setResolution).
Some usages of setResolution can't be removed yet because they are used
for fallback.

It makes more sense to have it in the AssetLoader now that decoding is
done there, particularly as the decoder factory should rarely be
customized.
Also remove the setter from the AssetLoader.Factory because it's
uncommon to have setters in a factory.

The old names are not really correct anymore because:
- The Audio/VideoTranscodingSamplePipelines do not decode anymore.
- The pipelines now mux the encoded data.

Before, it was possible for onDurationUs() and onAllTracksRegistered()
to be called before onTrackAdded() because they are called from
different threads. onDurationUs() and onAllTracksRegistered() are called
from the Transformer internal thread, and onTrackAdded() is called from
the playback thread.

AssetLoader declares the tracks with a setTrackCount() method. Setting
the track count on the FallbackListener is easier than calling
registerTrack() as many times as the number of tracks.

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.

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.

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.
