From this CL on, FrameProcessor listeners will be invoked from an Executor that
is passed in when creating the FrameProcessor.
GlTextureProcessor needs to invoke the ErrorListener on the said Executor too.

Most demo videos aren't very long, and the default demo video is only 10 seconds.
Shorten the maximum trim duration to 10 seconds, to demonstrate transformer functionality more easily, and allow this to be used more easily when trimming short sections of a longer video (ex. to make test clips)

Player controls are somewhat distracting when showing the difference between the
input and output video, as they obscure and darken the video players.

Before, slider values were read as `floor()`'ed `longValue()`s, so that trimming to
intervals less than one second would be interpreted as a request for a zero-
duration trim.
Also, rename `radiusRange` references here to `trimRange`, since this is not a
radius range.

This change adds a new method onReadyToAcceptInputFrame to
GlTextureProcesssor.InputListener and changes maybeQueueInputFrame
to queueInputFrame, removing the boolean return value.
This avoids the re-trying in ChainingGlTextureProcessorListener
by allowing it to only feed frames from the producing to the consuming
GlTextureProcessor when there is capacity.
MediaPipeProcessor still needs re-trying when processing isn't 1:1.

Without this permission, files in `/sdcard` or other directories cannot be read by the demo, as they're not in the transformer demo's scoped storage container.
For more information, see https://developer.android.com/training/data-storage/use-cases
Tested by uninstalling and re-installing the demo app, granting permission by
starting a transformation, and launching an intent using a local file in `/sdcard`
to start another transformation. Without this CL, this threw an error, and with
this CL it succeeded.

This simplifies ChainingGlTextureProcessor as it now only connects a
consuming and a producing GlTextureProcessor rather than a previous,
current, and next GlTextureProcessor.
Also use default no-op implementations of the listeners in
SingleFrameGlTextureProcessor and MediaPipeProcessor to avoid
null-checks.

This will allow effects preview in ExoPlayer to use the
Effect and FrameProcessor interface (and the interfaces
they depend on) without depending on transformer or the
future effects module.

Size requires API 21. Using Pair instead will allow effects to be
used from API 18 during previewing once they are moved out of
transformer.

This is needed for applying effects to a playlist.
The effects are applied based on the presentation time of the
frame in its corresponding media item and the offset is added
back before encoding.
Each time the offset changes, end of input stream is signalled
to the texture processors. This is needed because the texture
processors can expect monotonically increasing timestamp within
the same input stream but when the offset changes, the timstamps
jump back to 0.

This allows us to use BT.2020 RGB linear for intermediate shaders, which also
allows us to re-enable PeriodicVignetteProcessor, which should work properly in
linear color-spaces.
Manually tested by adding a GlEffectsWrapper, and confirming that HLG HDR editing still looks correct.

* Introduced `useHdr` for `GlEffect#toGlTextureProcessor`, so
`TextureProcessor` implementations can decide how to handle HDR.
* Creating FP16 color textures for HDR input.
Tested via manual testing, adding a no-op GlEffectWrapper to the transformation to
force use of intermediate textures, adding a linear ramp to the fragment shader,
and trying to ascertain that there's a real reduction in posterization when
switching from 4-bit to 8-bit unsigned bytes, and again from 8-bit unsigned bytes
to 16-bit floating point.

The old URL doesn't correctly signal the HDR10 color info in the container.
The new URL signals ST2084 (PQ) transfer function and BT.2020 color space as expected.

The GlEffectsFrameProcessor that will be part of the effects module
uses the DebugViewProvider. So it does not make sense for it
to be an inner interface of Transformer.
