    Description

      According to [MFShutdown function (mfapi.h) - Win32 apps | Microsoft Learn|https://learn.microsoft.com/en-us/windows/win32/api/mfapi/nf-mfapi-mfshutdown], FMStartup and MFShutdown should not be called during static destruction.

      The consequence of doing so is crashes during shutdown or failure to call remaining destructors. See for example QTBUG-120198.

      The goal is to shut down WMF when the QApplication shuts down. This requires structural refactoring of the different backends.
