[Merge-M53] arc: Support window recreation.

In some cases, Arc window may be destroyed and created again. This
leads to situation when shelf item is closed and there is no longer
item for Arc task. This CL allows Arc window to be recreated. The
situation may go even worse, window may be destroyed and not created
after. In this case we have task without window. In this case, we
send launch request to Android and this put Android task to foreground
and window is created.

BUG=b/31071902
TEST=Manually on device, installed several photo editor apps as
     described in task. Minimize/maximize window. Sometimes window
     get destroyed and created again. Shelf item is not lost in this
     case. Sometimes window destroyed and not recreated. Shelf icon
     still exists and clicking on it gets new window back for task.
TEST=Extended unit_tests
