ivi-shell: transform refactoring, remove transform part of ivi_layout_surface and ivi_layout_layer once

To refactor transform of ivi_layout_surface and ivi_layout_surface to be
more readable logical flow.

Remove following parts once,
* definition of weston_transform in ivi_layout_surface
* update_layer_orientation
* update_layer_position
* update_surface_position
* update_surface_orientation
* update_scale
