Allow std::set<> C# typemaps to work for non-nullable types too

Browse source 
Notably make them work for primitive types, such as "int".

Doing this requires using "object" instead of the actual C# type of the
variable to store the current value in the iterator, as we don't
currently have a "csnullabletype" typemap that would expand to "T" for
nullable types and "T?" for the other ones. This is a bit ugly, but it
shouldn't matter much for the generated code and is already done in
std::vector<> typemaps.

Also add a simple unit test verifying the basic functionality for such
vectors.

Closes #1568.
