Disable OGG and MP3 looping by default on import

* From Godot 4.0 onwards, proper music looping is supported which requires setting the BPM and then the loop point in beats.
* As such, importing with loop by default does not serve much of a purpose. Its annoying to disable for SFX or clips that do not loop and it also requires manual intervention to loop music.
* This way, it should work out of the box for any sound effect or non looping audio clip, and manual work is required anyway for looping music.
