Remove [NoInterfaceObject] from several WebAudio IDL interfaces

Remove [NoInterfaceObject] from several WebAudio IDL interfaces

Several WebAudio IDL interfaces had [NoInterfaceObject] extended attribute set,
meaning that there was no corresponding attribute on the global window object.
This behavior is not according to the specification:
https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html

This patch removes the [NoInterfaceObject] extended attribute where needed to
match the specification.

lgtm - guess this was just a mistake from a couple days ago?

Not really, there was no attribute on DOMWindow.idl corresponding those IDL
interfaces AFAIK. Therefore, they were implicitly behaving as NoInterfaceObject
already. My patch from a few days ago just made it more explicit and more
obvious that it does not match the spec.
