huangdarwin e5ef31b277 Effect: Avoid allocating bitmaps and textures in Overlays.
In `TextOverlay` and `DrawableOverlay`, treat `Bitmap` as a buffer, where we
allocate it rarely and reuse it as long as possible before making a new one.

In `BitmapOverlay`, avoid allocating GL textures too often as well.

Strongly reduces allocations and memory usage growth (saving ~100-150 MB on 4k60fps
at high end), at the cost of more code complexity and low-end using 70MB more, on
1/1 comparisons.

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.
