Add Test Coverage For MFC ActiveX Controls

[lonitra]

Related: #8294

This is another area we are lacking as we do not have any MFC ActiveX test coverage. Any help here is appreciated!

As a first step an MFC ActiveX control will need to be created, registered, and follow a pattern similar to #8253 to get it into the winforms solution. The gaps for test coverage can then be expanded from there :)

duplicate of #8294 ? either way I'll probably contribute some as part of #10583 to get COM source generator based ActiveX bindings working

I'll be stepping away from this issue for now. If there are any future developments or if the need arises to revisit it, please feel free to do so.
