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.

So far we have only wxMSW-specific implementation (and also a trivial
wxUniv-specific one) but it's still tidier to have all platform-specific code
in separate files, especially as we're going to have more of it for wxMSW
soon.
