Expose AudioStreamPlayer{2D,3D}::set_playing and remove AudioStreamPlayer::{2D,3D}::_is_active

- The `_is_active` method seems to be unused, so it was removed.
- The `_set_playing` method is now exposed, as the setter of the `playing` property.
    - The `play` method can't be used as a setter because it takes a `float` parameter instead of a `bool` parameter.
