Replace wxControlContainer-related macros with wxNavigationEnabled<>.

Simply inherit classes which need to provide TAB navigation among their
children from wxNavigationEnabled<> and remove the now unnecessary
WX_DECLARE_CONTROL_CONTAINER() macros.

Also remove WX_INIT_CONTROL_CONTAINER(), WX_DELEGATE_TO_CONTROL_CONTAINER()
and WX_EVENT_TABLE_CONTROL_CONTAINER() which are not needed neither any more.

And remove the event tables which became empty after removing the last macro.
