A callback used to free resources when a property is deleted.
This should release any resources associated with value that are no longer needed.
This callback is set per-property. Different properties in the same group can have different cleanup callbacks.
This callback will be called *during* SDL_SetPointerPropertyWithCleanup if the function fails for any reason.
