ivi-shell: convert from screen to global coordinates

Browse source 
In single screen, the coordinates of layer local coordinates are the
same as global coordinates. However, to support multi screens, the
layer-local coordinates shall be transformed to multi screen coordinates,
which is global coordinates. The abosolute coordinates of a screen in global
stored in (x,y) of output of its weston output so it shall be used to
transform layer-local to global coordinates.
