* Rename all Rgba instances to Rgb.
* Remove alpha value from the RGBA Matrices and apply the 4x4 matrix
only to the R, G, B channels.
* Restore the alpha from the input unchanged.

(cherry picked from commit 8760ee48)

This change adds ExternalTextureManager which implements
InputListener to only queue input frames to the
ExternalTextureProcessor when it is ready to accept an input
frame. This replaces the old retry-logic in GlEffectsFrameProcessor.

Before this change, the retrying in GlEffectFrameProcessor wasted
CPU time if input becomes available faster than the
ExternalTextureProcessor can process it.

From NDK 23.1.7779620 and above, the arm64-v8a ABI needs additional
build flags to correctly link the ffmpeg libraries.

In some cases, the IMA SDK fails to call the expected loadAd
event to load the next ad to play. This is (potentially) the
only remaining case where playback can get stuck due to missing
calls from IMA as the player doesn't even have a MediaSource at
this stage and is only waiting for IMA to provide the ad URL.

We can reuse the existing adPreloadTimeoutMs that was added for
a similar purpose (when preloading the first ad in the group).
The JavaDoc matches this purpose as well and the default timeout
is appropriate since we expect to get the loadAd call immediately.

createSupportedTransformationRequest is more accurate than
createFallbackTransformationRequest, as a TransformationRequest will be returned
regardless of whether any fallback is applied.

(cherry picked from commit c5a53646)

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.

Previously, this feature interpreted SDR signals as HDR when called. Now, only HDR
streams are interpreted as HDR, so the javadoc should be updated. Not yet removing
this method, as there are still some loose ends to finish up (ex. PQ support, e2e
tests).

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.

While HDR is most closely tied to the color transfer (ex.
COLOR_TRANSFER_SDR is the only one explicitly mentioning dynamic
range), technically color spaces may be associated with HDR as well,
like BT.2020 commonly being used for HDR rather than BT.709 for SDR.

Therefore, it's more specific to mention just that the transfer is HDR.

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 allows the GlEffectsFrameProcessor to later handle HLG and PQ
differently, or limited and full color range differently.

No functional change intended in this CL.

In the case where this check fails, the downstream frame processor chain won't be able to handle the incoming (SDR) data anyway as we've already set it up for HDR.

The encoder color info [defaults](https://cs.android.com/android/platform/superproject/+/master:frameworks/av/media/libstagefright/foundation/ColorUtils.cpp;l=377;drc=891c19ccfa4953b5e5f7b87118e007b994d8074c) to a value that depends on the input resolution, but when tone-mapping is enabled we should always get BT.709 color space. Hard-code this constant for now to avoid behavior depending on the resolution. A future change should use the decoder output media format to populate the color info.

Format.NO_VALUE is a placeholder value for an invalid @C.ColorTransfer, used
for example when the decoder doesn't support this transfer function.

When encountering this invalid value, interpret this as COLOR_TRANSFER_SDR.

Confirmed locally that an exception is thrown when transcoding on p4head, and no exception is thrown when transcoding with this CL.
