ivi-shell: don't schedule compositor repaint

it is not necessary to repaint all outputs after
each commit_changes. Only outputs with modified
views has to be repainted.

We need to call weston_view_update_transform
for assigning views to outputs first.
Then, We can call weston_view_schedule_repaint
to trigger repaint for outputs.
