MP4 edit lists sometimes ask to start playback between two samples.
If this happens, we currently change the timestamp of the first
sample to zero to trim it (e.g. to display the first frame for a
slightly shorter period of time). However, we can't do this to audio
samples are they have an inherent duration and trimming them this
way is not possible.

Confirms that multiple textures can be output, and that timestamps and pixels
are as expected.

Mp4Muxer already supports writing Mp4LocationData so added that
as supported Metadata entry.
Support for more Metadata entries will be added in upcoming CLs.

Mp4Muxer supports adding Metadata track.
Added test file to cover this scenario.

This change adds end-to-end Robolectric playback tests which handle
the scenario the player is playing audio via passthrough and
AudioTrack raises the ERROR_DEAD_OBJECT error upon which the player
attempts to recover by switching to another audio format.

Previously, I assumed that SDR contents must be BT709, and HDR contents must be
BT2020. Turns out BT2020 is just wide-gamut, and SDR contents / transfers may be
represented in BT2020 color spaces.
Relax the check, so that we don't throw when valid BT2020 SMPTE 170M contents
are input into effects.

The actual csd data contains NAL units so it should always start with
a NAL unit start code (00 00 00 01).
This issue was not caught before because in the code there was no
validation to check whether its a valid NAL unit.

Simplify the audio encoder input timestamp calculation. The new calculation
avoids drifting by tracking the total number of bytes encoded rather than
tracking the timestamp and remainder separately, and also makes the timestamps
match the decoder output buffer timestamps.
Also switch one of the export tests that was passing through AMR samples over
to using WAVE audio. The problem with using AMR is that the compressed samples
are not necessarily an integer number of audio frames and the shadow decoder
would pass them from input to output, so the audio encoder was receiving
non-integer numbers of audio frames.
Tested by logging the timestamps at the decoder output and encoder input with
forcing transcoding audio, and verifying that after this change the audio
timestamps are no longer off by one.

The FakeExtractorOutput dumps data in more readable format
so using that where ever possible.
The MdtaMetadataEntry which contains key and value dumped only "key".
Added fix to dump "value" as well.

This was trimmed using the Transformer Demo, from ~4 seconds to 300ms
Otherwise, this test file will be quite large, and folks who clone the repo will
have to clone this content as well. Trimming the file also allows the test to
take less time, while still testing the core purpose of the file, to confirm that 4k extraction/decode/GL/encode/muxing works.

This test file used to be remote, which led to various errors in loading the file or timing out during the muxer or overall transformer.

With the Mp4Muxer, while writing a large file if the something unexpected happens and muxer is not closed properly then it still outputs a valid MP4 file with partial data.

- This is to make sure we know about all the tracks before initializing
the SamplePipelines. This allows to set the muxer and the fallback
listener track count before the SamplePipelines are built.
- As a result, the test files had to be updated because the order in
which the tracks are written has changed.
- The ImageAssetLoader also had to be updated to call onOutputFormat
repeatedly until it returns a non-null SampleConsumer.
- Also fix the trackCount sent to the muxer and fallback listener. The
correct track count can be computed now that we know about all the
tracks before building the SamplePipelines.

Renamed MuxerEndToEndTest.java to Mp4MuxerEndToEndTest.java to align it with class under test.
Removed muxed prefix from dump file name because Mp4 implicitely means muxed only.
