Add wxNumberFormatter class helping to deal with thousands separators.
wxNumberFormatter formats and parses numbers with thousands separators. Add the class itself as well as documentation and the unit test for it. See #12166. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@66710 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
