Move close() from BaseAudioContext to AudioContext

Move close() from BaseAudioContext to AudioContext

OfflineAudioContext cannot be closed so it makes more sense to have
close() be defined on AudioContext instead of BaseAudioContext.

This is a very minor tweak to the API, so no Blink intent submitted.

rtoy@chromium.org changed reviewers:
+ hongchan@chromium.org, tkent@chromium.org

[Raymond Toy, 2016-09-15 15:53:13]

hongchan: PTAL

tkent: Review as API owner; a very minor tweak to the API. The  only visible
change is that OfflineAudioContext.close() no longer exists, but all it ever did
was throw an error if used.

[hongchan, 2016-09-15 16:18:15]

lgtm

[tkent, 2016-09-15 22:12:56]

lgtm.  A minor web-exposed change, and almost no risk.
