Fix config change on secondary split adjustment

This adds some more config controls to containerTransaction so that
sysui divider can "freeze" the configuration w/h while it is
offset for IME.

Bug: 133381284
Bug: 149952263
Bug: 150400846
Test: Just after boot, open split with settings in secondary and
      open the search activity. This should show IME and not
      randomly hide it when background apps are started.
      Also added a wmtest.
