ivi-shell multi screen support

This patch enables ivi-shell to manage multi screen.
This solves SPEC-360 ivi-shell fails to manage two screens.
CES2017 cluster demo also requires multi screen support.

+Subject: [PATCH] ivi-shell: transforming from a single screen coordinates to
+ multi screen coordinates: global coordinates.
+
+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.
