[Sema] Set range end of constructors and destructors in template instantiations

Summary:
clang-tidy checks frequently use source ranges of functions.
The source range of constructors and destructors in template instantiations
is currently a single token.
The factory method for constructors and destructors does not allow the
end source location to be specified.
Set end location manually after creating instantiation.
