Fix tons of warnings in wxMSW after deprecating wxPen/wxBrush int styles &c.

Replacement of FUTURE_WXWIN_COMPATIBILITY_3_0 with WXWIN_COMPATIBILITY_3_0 in
r75532 resulted in tons of warnings as all code using wxSOLID and similar
constants now uses the deprecated methods taking int instead of the preferred
ones taking wx{Pen,Brush}Style (and similarly for wxFont{Style,Weight,Family}).

Fix all of them but this also would seem to mean that this change might not be
such a good idea at all.
