Currently we prefer technical preferences set in the Parameters over
content preferences implied by the media. It proably makes more
sense in the opposite order to avoid the situation where a
non-default track (e.g. commentary) is selected just because it
better matches some technical criteria.

Also add comments explaining the track selection logic stages.

When the input is not a slow motion video, then flattening should do
nothing, so there is no need to re-encode audio.

This is already called in GlUtil.Program().

Tested by confirming that the demo-gl target still runs as expected.

And also tweak existing role flag logic to strictly prefer perfect
matches over partial matches.

Caveat: Video role flags only supported for fixed track selections
(same issue as Issue: google/ExoPlayer#9519).

This allows to check if the media metrics service is available outside
the actual constructor and to fail gracefully if it is missing.

- This format is passed to the PassthroughPipeline, which doesn't use
  any decoder.
- In most other cases where it is used, it is not relevant that this
  format will be or has been passed to the decoder. What's relevant is
  that it is the format of the input.

We need the filename of the output videos to be predictable, because
MobileHarness requires the exact filename to pull the file.

Deprecates setContext() and moves the required Context arg into the constructor.

This way, the parameter can later be final and non-null, per the comment at:
http://go/https://github.com/androidx/media/commit/79f03bb1355b7e370991a1aafd580324d22e070e/depot/google3/third_party/java_src/android_libs/media/libraries/transformer/src/main/java/androidx/media3/transformer/TranscodingTransformer.java?left=s19&right=r12#97L

Also, fixes setOutputMimeType_unsupportedMimeType_throws by providing a context
in the builder, and updating the FrameworkMuxer#supportsOutputMimeType to catch
IllegalArgumentExceptions thrown by FrameworkMuxer#mimeTypeToMuxerOutputFormat.

Fixes the gradle compilation failures.

Gradle dependencies need revising if we want to be using this, as
checkerframework is ahead of their latest version, such that we
can't compile.

This change moves methods that are the same in
`TransformerAudioRenderer` and `TransformerVideoRenderer` to
`TransformerBaseRenderer`.

This inheritance is really confusing because ExoPlayerImpl is not
a full Player interface implementation. It also claims to be an
ExoPlayer implementation in the Javadoc which isn't true in its
current state.

Removing the inheritance also allows to clean up some unused methods.

This is documented on the setter already, but it seems to make sense to do this in the constructor as well for clarity.

Before this change ExpPlayerImplInternal dropped a change of the playing period when a change in the timeline occurred that actually changed the playing period but we don't want to update the period queue. This logic also dropped the update of a skipped server side inserted preroll ad for which we want the periodQueue to 'seek' to the stream position after the preroll ad and trigger a SKIP discontinuity.

This change now introduces an exception so that a skipped SSI ad is still causing an update in the period queue which leads to a 'seek' and a discontinuity of type SKIP.

Document that apps should retain `GlUtil.Program` while the program is in use,
and keep a reference to attributes/uniforms within the program to make sure
they don't get GC'd causing any allocated buffers passed to GL to become
invalid.

Tested manually by running gldemo and transformer.

The features supported by `TranscodingTransformer` are a
superset of those supported by `Transformer` after merging
the video renderers in
https://github.com/androidx/media/commit/35c891a7bf7c18d2b906fe6a3b0325ca74bcf91f.
This change removes `TranscodingTransformer` and adds its features to
`Transformer`.

Buffers that are useful to pass to the sample/passthrough pipeline
should either contain data or the end of input flag. Otherwise, passing
these buffers along is unnecessary and may even cause the decoder to
allocate a new input buffer which is wasteful.

The player will not play ads in final states (played, skipped, error)
again. To allow ads loader customizations to play ads again, we can
add a method that resets the state back to available or unavailable
(depending on whether we have the URI for the ad).
