Remove 2-arg createBuffer from WebAudio

Remove 2-arg createBuffer from WebAudio

Originally the 2-arg createBuffer method was a method for synchronously decoding a blob of encoded audio data. This is no longer allowed in the WebAudio specification.

See http://webaudio.github.io/web-audio-api/#methods for the valid createBuffer method.

Update tests accordingly.

PTAL. This is the last of the CLs I have planned for removing legacy webaudio
features.

This variable isn't needed anymore.
