temporary quickfix for issue #3473

Added new API to record and play events
Added examples illustrating functionality

This reverts commit 804f1a83eb.

closes https://github.com/raysan5/raylib/issues/3463

This reverts commit 8fbd42d592.

Additionally added a volume assignment from old to new as currently there is no way to get the volume of a sound and the AudioBuffer struct is not reachable from user code due to opaque definition.

rcore_desktop_sdl.c was not present in the list of prerequisites this
patch changes them to use a wildcard, so any other platforms added in
future will be tracked properly

ImageDrawCircleLinesV already existed, so I'm not sure why this was
missing. It is trivial to implement, anyway

This reverts commit c4fb6c8517.

This reverts commit da9bc564d2.
