This allows us to more easily create different dumps derived from the same assets. This moves media/source files from `assets/` to `assets/media/` and dump files from `assets/` to `assets/extractordumps/` and `assets/audiosinkdumps/` as appropriate. I intend to add `assets/playbackdumps/` in a future CL. PiperOrigin-RevId: 326986283
