SDK / exoplayer

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.

`requestCalculateSsim` more clearly represents the intention of the caller.

Also rephrase the javadoc to simplify it and make it more precise.

Adds a new event to AudioOffloadListener to get the offload state of the track, which indicates when software decoding is taking place.

(cherry picked from commit 78935318)

Avoids disabling Offload on a write error, and instead relies on this being disabled on the AudioTrack init. It will no longer recover by disabling offload.

* OpenGL automatically clamps the output colors to the [0, 1] interval.

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.

(cherry picked from commit 687a50e9)

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.

Despite unregistering the callback and clearing pending Handler
messages, the callback may still receive pending calls if they
are already triggered by the AudioTrack. Instead of asserting
that the track is correct, we should gracefully ignore stale
events.
