We currently call RoGetActivationFactory() on every single (wrapped) constructor or static function call.

This should be optimized by caching activation factories. An explanation of what's done in the modern C++ projection is given in https://kennykerr.ca/2016/11/24/cppwinrt-optimizing-activation/
