ivi-shell: hmi-controller supports multi screens at fullscreen mode.

It shows ivi applications in fullscreen per screen like,
The first screen: Application 1,4,5,6,,,,
The seconed screen: Application 2,
The third screen: Application 3

Thie mode assigns one application to each screen at first. And remaind
applications more than screens will be assigned to the first screen.
