Should use GetDllVersion for seeing what common controls is available

[JeremyKuhne]

In [Application.InitializeComCtlSupportsVisualStyles()] we're scraping for known exports to determine the version of common controls that is available. That's error prone and why they've added DllGetVersion to the various shell dlls. There shouldn't be a "binding" issue as called out in the code.
