Correct wxDC::GetContentScaleFactor() documentation

Browse source 
Document that it returns the same value as GetDPIScaleFactor() wxWindow
method and _not_ the wxWindow method with the same name.

This is very confusing, but there doesn't seem to be anything to be done
about it by now.

See #23441.
