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.

Main change:
- Removed `Codec.EncoderFactory.createForVideoEncoding`'s argument of a list
of allowed MIME types
- Moved the check for whether a video MIME type is supported to VTSP

This thread just starts the player and handles the player callbacks for
now. Sample pipelines are still run on the playback thread.

This reduces the priority to best effort (from the default that seems to be best effort), and allows us to run SSIM even on 8k24fps video. Without this CL,
start()'ing a second codec may result in a MediaCodec.CodecException.
Tested to confirm that transformation8k24():
* fails deterministically without this CL, or with KEY_PRIORITY set to 0.
* succeeds deterministically after this CL (~18s on Samsung Z Fold 4)

We cannot check this in code, due to DEVICE_INITIAL_SDK_INT being a @SystemApi, and
reflection being a bit risky/unstable.

The bug has since been fixed.
The values still could change, as the API is labelled as @UnstableApi, so it's
probably fine to leave the <p> tag mostly as is.

This allows us to release both codecs used in SSIM when one fails to
configure() or start().
Tested and confirmed that on Samsung Galaxy Z Flip 4, running all
TransformationTest.java tests, tests after transform8k24() fails to start the
2nd codec:
* Before this CL, all fail.
* After this CL, all pass.

This exception is a bit shorter and more clear (and is more clear that this is a
test issue, as opposed to the prior issue that was thrown as an ExoPlayer
DataSourceException, which may seem like a legitimate Transformer failure)

Following naming conventions throughout AndroidTestUtil, REMOTE files should have REMOTE instead of ASSET. Update the URI and FORMAT names accordingly.

AssetLoader will have multiple implementations and be customizable. We
want to remove the responsibility of computing the progress from this
class and centralize the logic in TransformerInternal.

Not setting the color info results in a missing "colr" box in the produced
container, under file/moov/trak/mdia/minf/stbl/stsd/hvc1. This means extractors
will not be able to find out the transcoded file is HDR.
In `Transformer`, this means it can't transcode this transcoded file, because
it currently relies on the container bearing HDR info to construct the
transcoding sample pipeline.

In startTransformation method we were throwing UnsupportedEncodingException (IOException) when mediaItem with unsupported arguments is passed.
Changed this to IllegalArgumentException which seems more logical here.

This logic is currently in the player renderers. With multi-asset, the
renderers will go into the AssetLoader, which shouldn't be responsible
for muxing.

Problem: We are initialising muxer as soon as we start the transformation. Now the startTransformation() method can be called from main thread, but muxer creation is an I/O operation and should be not be done on main thread.
Solution: Added lazy initialisation of muxer object. The actual transformation happens on background thread so the muxer will be initialised lazily from background thread only.
Another way was to provide an initialize() method on MuxerWrapper which will explicitly initialise muxer object but with this approach the caller need to call the initialise method before calling anything else. With current implementation the renderers are calling MuxerWrapper methods on various callbacks (Not sequentially) and also we are sharing same muxer with multiple renderers so It might become confusing for the caller on when to call the initialise() method. Also there are few methods on MuxerWrapper which dont really need muxer object. So in short it might make MuxerWrapper APIs more confusing.
Validation: Verified the transformation from demo app.

This should be necessary to ensure decoders see fewer errors.
Setting this resulted in removing native_dequeueOutputBuffer errors on OMX.MTK decoders for in-app tone mapping prototyping.
