Split single/multi line behaviour in Qt wxTextCtrl

Introduce wxQtEdit class and wxQtMultiLineEdit and wxQtSingleLineEdit
derived classes instead of using ifs in many wxTextCtrl methods, making
the code more clear and maintainable.

Also fix some wxTextCtrl-related unit test failures with wxQt and
disable some other ones which still don't pass.

Closes https://github.com/wxWidgets/wxWidgets/pull/1039
