Allow displaying Japanese character with wxMotif/ANSI under a

Japanese EUC-JP locale:

- add a #define (wxMOTIF_NEW_FONT_HANDLING) defaulting to
  off
- factor the code for getting text extents in a central
  wxGetTextExtent function
- when the new font handling is enabled load a fontset instead of
  a single font. For non-Japanese locales this should load a fontset
  containing a single font.
- on a Japanese locale set the default point size to 15: the Japanese
  fonts I have are much more readable like this.
- do not set the wordwrap property for multiline wxTextCtrl with
  OpenMotif 2.1, otherwise it crashes when text is added
