Add bindings for new audio engine of cocos2d-x

[zhaijialong]

wuhao think we should bind the new audio engine. But that will be jsb-only api, so should we add it? If we should , when? in 3.3? @pandamicro

Is the new APIs applicable in Web ?
We can evaluate the implementation and costs for both JSB and Web, but 3.3 features have been fixed, so we will discuss it for later versions

• Bind new audio engine in Cocos2d-x
• Implement new audio engine API with WebAudio if possible
