Bug 1435671 - Reduce binary size by making NS_MutateURI.Apply not be a templated method r=mayhemer

We instead add a templated method NS_MutatorMethod that returns a std::function<nsresult(nsIURIMutator*)> which Apply then calls with mMutator as an argument.
The function returned by NS_MutatorMethod performs a QueryInterface, then calls the passed method with arguments on the result.
