Implement Storage::SupportedPropertyNames

Hi guys,

This is a rough draft for issue #7670 .

It includes :
   - SupportedPropertyNames implementation
   - WPT with Object.supportedpropertynames with Local Storage and Session Storage.

The following link help me understood the issue :

https://html.spec.whatwg.org/multipage/infrastructure.html#supported-property-names

Thanks for looking into it.
