When the period has loaded to the end of the source, the `period.getBufferedPositionUs` will be set to `C.TIME_END_OF_SOURCE`, which is a negative value. Thus, the original `continueLoadingPredicate` will never turn to `false`, as the `bufferedPositionUs` is definitely less than the target preload position that is expected to be positive.

In this change, we added `PreloadMediaSource.PreloadControl.onLoadedToTheEndOfSource(PreloadMediaSource)` to indicate that the source has loaded to the end. This allows the `DefaultPreloadManager` and the custom `PreloadMediaSource.PreloadControl` implementations to preload the next source or take other actions.

This bug was not revealed by the the `DefaultPreloadManagerTest` because the related tests were all using the `FakeMediaSource` and only setting the preload target to `STAGE_TIMELINE_REFRESHED`. Thus, the tests for testing the `invalidate()` behaviors were modified to use the real progressive media whenever possible, unless we have to use `FakeMediaSource` to squeeze a chance to do more operations between the preloading of sources to test some special scenarios.

ExoPlayer module

This module provides ExoPlayer, the Player implementation for local media playback on Android.

Getting the module

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

implementation 'androidx.media3:media3-exoplayer: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.
