huangdarwin 99ae44efa4 Overlays: Create OverlayMatrixProvider.
Split this logic out from `OverlayShaderProgram`, to share logic like
this with `VideoCompositor`.

Also, remove the unused `context` parameter from `OverlayShaderProgram`

`VideoCompositor` will reuse `OverlayMatrixProvider`'s storing of the matrices,
though it may generate the matrices differently, since `OverlayShaderProgram`
applies this in the fragment shader, whereas `VideoCompositor` applies this in the
vertex shader.

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.
