Source/JavaScriptCore:

* JavaScriptCore.xcodeproj/project.pbxproj: Make JSPromise.h and JSPromiseResolver.h
private headers for WebCore to use.

* runtime/JSPromise.h:
* runtime/JSPromiseResolver.h:
Export functions that JSDOMPromise will use.

Source/WebCore:

This is not perfect, as it strongly ties DOM code to JavaScript. In the future, we
can make it better e.g. by subclassing, so that only a base interface would be exposed.

* WebCore.vcxproj/WebCore.vcxproj:
* WebCore.vcxproj/WebCore.vcxproj.filters:
* bindings/js/JSBindingsAllInOne.cpp:
