Refactor : Hide wayland operations from Window Manager

Window Manager now uses abstract client, area for layer/surface management,
then hide wayland operation into LayerControl class.
LayerControl class uses ilmControl library instead of wayland protocol.
This patch reduces the binary size of binding by 30% than before.

Currently, the following debug methods are not available.
* debug_status
* debug_layers
* debug_surfaces
* list_drawing_names

Bug-AGL: SPEC-1817
