Also, update tests to allow AnyOf error codes, and no longer check exception messages, which caused quite a bit of churn.

Assert that tone mapping is applied when an HDR edit cannot be HDR, but is successfully tone mapped. Meanwhile, assert that fallback, which is applied after codec configuration (which throws the "Tone-mapping requested but not supported by the decoder" error) is not applied when that error is called.

*** Original commit ***
Handle int instead of byte in SSIM.
The value of pixels are converted to integers at the point of use,
move this logic to the initialisation step.
This is a prerequisite step for testing SSIM calculation, which
will lead on to some SSIM improvements being verifiable.
Tested manually and SSIM values match for the same video
before and after this change.

Test that HDR editing succeeds on devices supporting HDR editing, tone maps on
devices supporting tone mapping, and throws exceptions on all other devices.
Also, only restrict HDR editing and tone mapping support to API 31+ only when
transcoding, not for all transformations.

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.

Effect and FrameProcessor interface (and the interfaces
they depend on) without depending on transformer or the

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.

It's always safe to ignore the result of these methods, because the
caller already has a reference to the returned value.

* 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.

This may happen when a containers' color transfer incorrectly does not match
the video's color transfer.
An example of a file with such a mismatch is the current Transformer demo HDR10
sample file.
Manually tested by confirming that no errors are emitted for SDR and HLG sample
files, and that errors are emitted for our incorrect HDR10 sample file.

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.

videoEncoderFormatUnsupported_completesWithError() has recently
been flaky on API 31 emulators on presubmit because a different
exception than the expected exception is thrown.
This disables it on those emulators to reduce testing noise
until the underlying problem is investigated and resolved.

After this change GlEffects can use any GlTextureProcessor not just
SingleFrameGlTextureProcessor.
MediaPipeProcessor now implements GlTextureProcessor directly which
allows it to reuse MediaPipe's output texture for its output texture
and avoids an extra copy shader step.
