Return full virtual screen size from wxScreenDC::GetSize() in wxMSW

Browse Source 
Return the size of the entire virtual screen, possibly composed from multiple
monitors, rather than just the size of the primary monitor.

This makes this method consistent with wxScreenDC actually representing the
entire virtual screen and not just the primary monitor and also with wxGTK.

Closes #13279.
