Keep the WinRT specific parts for WinRT only. This commit is a partial
reversal of 67c83f329e "Tighten Q_OS_WINRT
ifdefs in qfunctions_winrt.h", which let the WinRT definitions out too
wide.
Strictly speaking, the C++ code that uses
Microsoft::WRL::ComPtr<IAsyncInfo> without the #include is broken. The
forward definition is not enough, but since Visual Studio is also
broken, two wrongs made a right... (MSVC does not implement two-stage
parsing of template code properly). But if you accidentally tried to
compile qfunctions_winrt.h with a non-broken compiler, like GCC (MinGW),
it would correctly complain.
