Reviewed by Carlos Garcia Campos.

This commit implements an API to create promises in JSC GLib.
It is a copy from the Objective-C valueWithNewPromiseInContext.
An executor is required, it will be invoked during promise initialization
and it receives the @resolve and @reject objects than can be called to resolve
or reject the promise. It is called like a js function, so exceptions raised
during the executor invocation will not be propagated to the context, but
handled by the promise causing a rejection.
