ivi-shell: add commit_current into ivi_layout interface

If a client commits a null buffer, weston will unmap all the views of
the surface and marks it is unmapping. In the case, the client commits
a new valid buffer, then the controller wants to rebuild the views
without applies the pending properties of surfaces and layers.
The ivi_layout_interface should prodive an interface for this.
