Improve selection and focus events generation in wxGenericLisCtrl
Avoid sending spurious wxEVT_LIST_ITEM_{FOCUSED, SELECTED, DESELECTED} events and make the generic version consistent with the behaviour of the native wxMSW one. Also add/extend the tests and slightly improve the sample. Closes https://github.com/wxWidgets/wxWidgets/pull/2044
