After this change GlEffects can use any GlTextureProcessor not just
SingleFrameGlTextureProcessor.
MediaPipeProcessor now implements GlTextureProcessor directly which
allows it to reuse MediaPipe's output texture for its output texture
and avoids an extra copy shader step.

After this change, FrameProcessorChain chains any GlTextureProcessors
instead of only SingleFrameGlTextureProcessors.

The GlTextureProcessors are chained in a bidirectional manner using
ChainingGlTextureProcessorListener to feed input and output related
events forward and release events backwards.

The offload sleeping stops as soon as a new DO_SOME_WORK message
is handled (because this indicates an expected change in rendering
and we want to stop sleeping until we know it's safe to do so).

Every exit path from doSomeWork needs to clear other pending
DO_SOME_WORK messages as these requests have already been handled by
the current method invocation. This currently doesn't happen from the
offload sleeping return path and a previously queued DO_SOME_WORK
message can immediately wake up the rendering loop again.

Fix this by moving the message removal to the beginning of the
doSomeWork method (as it prevents forgetting it in one of the
exit paths later).

This is useful for testing Transformer in the same way as it is used
in tests and to see only the real transformation time.

In follow-ups the FrameProcessorChain will set an instance of this
listener for each GlTextureProcessor to chain it with its previous
and next GlTextureProcesssor.

Fixing lint errors in the string.xml files makes no sense because these are
overridden with the next automated string import. Adding a lint-baseline.xml
instead for the ui module.

The wrapper
* catches exceptions for each task and notifies the
  listener (this will be used more in follow-ups when processFrame
  is split into lots of listeners and callbacks),
* removes finished tasks from the queue and signals any exceptions
  that occurred to the listener each time a new task is executed.

This change adds a SurfaceProvider interface which is necessary to
allow for texture processors whose output size becomes available
asynchronously in follow-ups.
VTSP's implementation of this interface wraps the encoder and provides
its input surface together with the output frame width, height, and
orientation as used for encoder configuration.
The FrameProcessorChain converts the output frames to the provided
orientation and resolution using a ScaleToFitTransformation and
Presentation replacing EncoderCompatibilityTransformation.

- Fixed MidiExtractor state issues which caused seeking to behave unexpectedly. Ensures the extractor is now always in the file loading state after returning RESULT_END_OF_INPUT.
- Fixed an infinite loop in MidiExtractor caused by the file data array having an initial size of 0. The extractor attempted to increase the capacity of the array by using this size of 0 in it's calculations.

The native GL errors are in an arbitrary order according to
https://www.khronos.org/registry/OpenGL-Refpages/es2.0/xhtml/glGetError.xml
This means any of them could contain the most useful message
so it's better to use all for the GlException's message rather than
picking the last message and logging all others.

`codecDrainAction` is set to `DRAIN_ACTION_NONE` in 3 places in
`MediaCodecRenderer`:
* The constructor (so there's no prior state to worry about)
* `updateDrmSessionV23()`: Where `mediaCrypto` is reconfigured based
  on `sourceDrmSession` and `codecDrmSession` is also updated to
  `sourceDrmSession`.
* `resetCodecStateForFlush()`: Where (before this change) the action
  is unconditionally set back to `DRAIN_ACTION_NONE` and so any
  required updated implied by
  `DRAIN_ACTION_FLUSH_AND_UPDATE_DRM_SESSION` is not done.

This change ensures that `flushOrReleaseCodec()` handles
`DRAIN_ACTION_FLUSH_AND_UPDATE_DRM_SESSION` before calling .

Based on
https://developer.android.com/reference/android/media/MediaCodec#using-an-output-surface,
frame dropping behaviour depends on the target SDK version.
After this change transformer will only use
MediaFormat#KEY_ALLOW_FRAME_DROP if both the target and system SDK
version are at least 29 and default to its pre 29 behaviour where each
decoder output frame must be processed before a new one is rendered
to prevent frame dropping otherwise.

Also remove deprecated Transformer.Builder constructor without a
context and the context setter.

Transformer always enabled glAssertionsEnabled, so there should
be no functional change.

ExoPlayer previously disabled glAssertionsEnabled, so GlUtil logged
GlExceptions instead of throwing them. The GlExceptions are now
caught and logged by the callers so that there should also be no
functional change overall.

This change also replaces EGLSurfaceTexture#GlException with
GlUtil#GlException.
