Add plugin name as a prefix for callback traits

[Ghamza-Jd]

Add plugin name as a prefix for callback traits so we don't have name collisions when a class implements 2 different callback protocols

For example, the on_other is present in the videoroom and audiobridge plugins, that means the swift protocol and kotlin interface will have onOther

Solution:
Add plugin name, so on_audio_bridge_other and on_video_room_other
