Fix focus handling logic in generic wxListCtrl.

Don't override SetFocus() to set the focus to the main window, this isn't
enough as we can be given the focus by the underlying toolkit itself, without
our SetFocus() being called -- this happened in wxGTK when focus was changed
from the keyboard using TAB and in this case it didn't get to the main window
but remaining on the wxListCtrl itself meaning that keyboard input wasn't
processed at all.

Use wxNavigationEnabled<> now to ensure that OnSetFocus() and related methods
do the right thing instead now.

Also get rid of OnSetFocus() in wxListHeaderWindow, it's better to override
AcceptsFocus() to return false to avoid getting focus in the first place.
