Rather than addressing numerous code analysis warnings Microsoft Visual
Studio 2019 reports for wxWidgets upstream, disable code analysis for
the time being. But only for the wxWidgets part. We still want to know
what the code analysis has to say about our code.

The GetDpiForWindow() Win32 API was introduced in User32.dll with
Windows 10. Since we have a fallback case when this API is not present,
avoid popping up the wxWidgets warning. Furthermore, performance was
improved by introducing a flag to prevent keep looking for
GetDpiForWindow() on each call.
