Don't use deprecated wxBOLD, wxNORMAL and similar constants.

Replace them with wxFONTWEIGHT_BOLD, wxFONTSTYLE_NORMAL or wxFONTWEIGHT_NORMAL
and equivalents in the code of the library itself and in the samples.

Also simplify font construction using wxFontInfo where possible to avoid
specifying these constants at all if they are not needed.
