Someone who cares about Windows/MSVC may want to take the mantle here, because 
cpp-winrt will be disabled for C++17. I don't know what cpp-winrt does (it 
doesn't seem to be necessary for MinGW, therefore it isn't *necessary*) but 
someone thought it was interesting to have in the first place.

There are 35 QT_CONFIG(cpp_winrt) checks in qtbase, the majority of which in 
the QPA plugin and in the networklistmanager plugin. All of those will now use 
the fallback code (if any).
