Reviewed by Geoffrey Garen.

Source/WebCore:

Get rid of custom code for webkitAudioContext global constructor getter. The
global DOMWindow attribute is now automatically generated by leveraging support
for [EnabledAtRuntime] extended attribute and the existing methods in
RuntimeEnabledFeatures class.

No new tests, no behavior change.

* GNUmakefile.list.am: Remove JSDOMWindowWebAudioCustom.*.
* Modules/webaudio/AudioContext.idl:
Remove [NoInterfaceObject] extended attribute so that the global constructor is
automatically generated instead of automatically added. Add [EnabledAtRuntime]
extended attribute since this global constructor can be disabled at runtime and
so that we can getter rid of the [CustomGetter] for the corresponding global
constructor. Use [InterfaceName] extended attribute so that the interface name
matches the global constructor on DOMWindow (webkitAudioContext).

* Target.pri: Remove JSDOMWindowWebAudioCustom.*.
* UseJSC.cmake: Remove JSDOMWindowWebAudioCustom.*.
* WebCore.exp.in: Export additional symbol.

* bindings/js/JSBindingsAllInOne.cpp: Remove JSDOMWindowWebAudioCustom.*.
* bindings/js/JSDOMWindowWebAudioCustom.cpp: Removed. We no longer need any custom code for
the WebAudio global constructor getter because we use [EnabledAtRuntime] support in the
bindings generator now.
* page/DOMWindow.idl: Remove global constructor for AudioContext as it is now automatically
generated.
* page/Settings.in: Remove webAudioEnabled setting as we use the existing setting
in RuntimeEnabledFeatures now.
