Prevent mesh surface point sampling hanging on degenerate triangles, by switching to non-rejection-sampling in that case. (Leave rejection sampling as-is for all other cases, to preserve exact same sampling behavior otherwise)

* Moved dllapi from types to functions/static vars
* Changed so extern template instantiation is based on clang or not instead of if linux and mac since we also build windows using clang
* Added dllapi on some member functions inside template types where the code is in the cpp file. This is needed to tell the compiler these functions will be dll exported (clang does not accept only adding it on the instantiation
