huangdarwin 2ad07e88ee HDR: Add PQ support.

Use the PQ OETF and EOTF to ensure that intermediate fragment shader operations
using PQ are in linear BT.2020 rather than PQ and HLG-1 BT.2020.

Also, swap the OETF and EOTF in shaders, as they were used incorrectly before

Manually tested by verifying transformer demo HLG and PQ videos look the same with and without this CL, including with a BitmapOverlayProcessor enabled to test flows both with one MatrixTransformationProcessor that skips HDR TFs, and with one that doesn't.

Effect module

Provides functionality for applying effects to video frames.

Getting the module

The easiest way to get the module is to add it as a gradle dependency:

implementation 'androidx.media3:media3-effect:1.X.X'

where 1.X.X is the version, which must match the version of the other media modules being used.

Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the top level README.
