[2/3] av: Audio Themes Support

On the Java side, Android has support for both a
Video Record Start sound, and a different Video
Record Stop sound. However, this part here only
supports one video recording sound.
We added support for RECORDING_STOP sound (by default,
the same as RECORDING).

PS1: added back media file and add separate condition for check  User-selectable camera click sound
