[swift-evolution] Name disambiguation of computed property/function with same type defined in extensions

This only introduces a new kind of ambiguity since you can have both ModuleA and ModuleB declare something like

class String {
	/// ...
}

And now you have no idea if ModuleA.String refers to Swift.String extension in ModuleA or class String in ModuleA.
