Previously, TextureMangers have a method to signal ending of a current input
stream, and a method to end the **entire input**. The responsibility of both
methods are not easy to document, understand and read.
With the new design,
- Only `TextureManager.signalEndOfCurrentInputStream()` is kept
- It's called for every MediaItem in the sequence, include the final one
- FinalWrapper now takes explicit signal that frame processing is ending,
rather than relying on the return value of `onCurrentInputStreamProcessed()`
- On DVFP receiving EOS from the pipeline, it signals FinalWrapper the stream
is ending, **before** signaling the input switcher, so that FinalWrapper is
able to end the stream when the onCurrentInputStreamEnded signal eventually
reaches FinalWrapper

This helps debug bitmap tests. Without this CL, I typically
need to go into the file to find the test name and absolute
path. With this CL, I can just adb pull the printed file path,
which is much simpler.

Partially roll forward of 5c29abbbf4, and adds some extra logic
Changes to the original CL
The original logic (a66f08ba97) fails in the following case:
> This is only seem on emulators.
- EOS is sent to ExtTexMgr
- The timer starts
- One frame arrives on SurfaceTexture, reset the timer
- The frame is sent for processing, now `availablFrames == 0`
- One frame arrives on Surface, reset the timer
- The frame is kept on SurfaceTexture for the downstream shader doesn't have
capacity, `availablFrames == 1`
- Timer times out as the downstream processor doesn't report being able to take
another frame.
- Although there's a frame available on the SurfaceTexture
This is solved by having the force EOS logic clear all the frames that the
SurfaceTexture holds. This also ensures the first frame dequeued from the next
stream isn't from the previous stream.

`outputSurfaceInfoChanged` is not reset when `defaultShaderProgram` is null.
That is, on the first time `ensureConfigured()` is called with output size
changed, `outputSurfaceInfoChanged` is not set to false after creating the
`defaultShaderProgram`, and `defaultShaderProgram` will be created again on the
second time `ensureConfigured()` is called.

This future.get() duplicates the wait done in
singleThreadExecutorService.awaitTermination(). If awaitTermination times out, this future.get() would also result in unnecessary blocking.

Also, document that texture output disables manual frame release.
In the past, texture output would lead to surface output methods throwing. Now,
they're simply no-ops instead.

This allows us to avoid needing a reference to the VideoFrameProcessor, which
can be especially difficult if an App only has a reference to the
VideoFrameProcessor.Factory it passes into Transformer/ExoPlayer.

Have the FinalShaderProgramWrapper / VideoFrameProcessor texture
output access textures provided through a texture pool, that
recycles used textures.
Also, add the TexturePool interface to generally re-use textures.

Propagate the "end of current stream" signal directly after queueing the
last frame, instead of waiting for the next onReadyToAcceptInputFrame()
call.

Allow the VideoFrameProcessor to output multiple textures at a time, so that
lifetime of textures is up to the consumer calling VFP.releaseOutputFrame.
The FinalShaderProgramWrapper also has a new maxCapacity limit added, to ensure
the a reasonable amount of textures is used and avoid using up memory.

When exporting compositions with multiple images in a row, transformation could
get stuck if a shader was ready to accept input when end-of-stream was already
signaled and queued from upstream. Fix accounting for the downstream capacity.
Manually tested on concatenations with several images and several videos in a
row, by adding logging and verifying the capacity updates as expected across
edited media item transitions.

The output end-of-stream notification from the last shader could theoretically
arrive before the latch for detecting it is created, which might cause waiting
on the latch indefinitely. Create the latch before signaling end of stream so
that it's guaranteed to be set before the end-of-stream signal arrives.

Also make FinalShaderProgramWrapper always receive internal texture.
This means it does not sample from a input texture, and its input color is
always linear, hence the input type does not matter.

*** Original commit ***
Effect: glFlush instead of glFinish on tex output
This is much faster (~2-3x) than glFlush. While there's a risk that GL commands
queued to the GL server may not be complete by the time non-GL commands access
the texture, this should be unlikely as we only access the texture from GL.
If we see stability issues in the future, we can reconsider and move this back
to glFinish (or GL synchronization mechanisms like fences, which are more
complex)

renderOutputFrame actually renders frames to an output surface. We'll soon have
a releaseOutputFrame method, that would release resources associated with an
output time, so rename this to disambiguate the two methods.
Also rename onOutputFrameAvailable to onOutputFrameAvailableForRendering, to
make it clear this is not available for "release"
This change should be a renaming-only change and have no functional differences.

Add `VideoFrameProcessor.registerInputStream()` to signal a new type of input.
And `InputHandler.signalEndOfCurrentInputStream()` to signal to `InputHandler`
partial input stream completion.
Fully processed means after FinalShaderProgramWrapper releases the last frame.
