This change splits AdvancedFrameProcessor into 4 files:
- MatrixTransformationFrameProcessor for the GlFrameProcessor
implementation
- MatrixTransformation and GlMatrixTransformation for the GlEffect
specification
- MatrixUtils for the static matrix helpers

Developers are expected to (eventually) only use methods on
PlayerView (and not PlayerControlView) to interact with the UI
controller.

This fixes some small niggles:
1. `inferContentType(String)` is documented to take a path, but in the
tests we're passing full URIs.
2. A `String` parameter is usually a path, but also a MIME type or an
extension. In the new methods, the meaning of a `String` parameter
is always clear from the name of the method.
3. `inferContentType(String)` is always passed an extension in
'production' code (which has to be manually prefixed with a dot).
4. `inferContentType(Uri, @Nullable String)` always ignores the Uri if
the String is non-null. IMO this logic is clearer to a reader if it's
just in-lined at the call-site.
These methods are used from the demo apps, so will be part of the stable
API.

Add a very short (1 second) video, so that some manual tests / prototyping,
including tests for the start and end of a video, encoder selection, or
changes applied to frames, can finish quickly.

What a minimal implementation should include is now explained in the
interface javadoc while the method name reflects what the method does.

The new demo GlFrameProcessor is based on BitmapOverlayVideoProcessor
from the gl-demo. The demo-only GlFrameProcessor can be deleted once
Transformer supports this functionality.

PeriodicDimmingFrameProcessor is an example of how a custom fragment
shader can be used to apply color changes that change over time.

The matrix provider allows the transformation matrix to be updated
for each frame based on the timestamp.
The following example effects using this were added to the demo:
* a zoom-in transition for the start of the video,
* cropping a rotating rectangular frame portion,
* rotating the frame around the y-axis in 3D.

Util.SDK_INT will not be part of the stable API. This change only
touches those parts of the main demo app that will not be opted-in to
the unstable API for other reasons (e.g. download use-cases).

From Android T onwards `MediaCodec` supports requesting tone-mapping down to
SDR. Add an option to request this behavior and document that it isn't
supported before T. Also add an option in the demo app to try it out.
Tested manually on a prerelease build.

This change rewrites the UI module's track selection
components to depend on the Player API, allowing us to
finally remove the UI module's dependency on ExoPlayer
as a concrete player implementation.

The muxer doesn't support HEVC below API 24. The is documented in
the TransformationRequest javadoc and the Transformer.Builder will
throw if HEVC is requested below API 24 so the option should not
be part of the demo for those devices.

isTypeSupportedOrEmpty is very specific and a little hard to
understand unless you know the one thing it's useful for. This
commit replaces it with isTypeSupported, which can be used in
conjunction with the recently added containsType method.

- The resources were released twice before, which is not necessary since
the MSG_RELEASE message is already in the internal player queue.
- The demo app was failing because the stop watch was stopped in
onTransformationError after being reset.

On Samsung S21 with light theme the debug labels weren't showing up because the player view was visible (with a black background) while the transformation was in progress, matching the debug label text color. Hide the player view until the transformation is complete to fix this.
Also tweak the layout slightly to add space between the card border and the labels.

This change makes GlUtil.Program an outer class named GlProgram,
and also moves private static helpers as well as the inner classes
Attribute and Uniform which were only used by GlUtil.Program to
GlProgram. Other static utility methods remain in GlUtil.
No functional changes intended.

scoped-storage directory on a:
* Nexus 6P API 23 emulator
* Google Pixel 4 API 31 physical device
