arc: Prevent App list popping on each app installed from batch.

There is possibility to manually install packages in batch mode.
In this mode App list is shown on each package installation. This
is annoying for user. This CL show App launcher only for first
installed in batch app. If user does not close App list he may
observer how next apps appear in list. If he closes it, now App
list will be shown unless next batch installation is started.
This also introduces new mojo notifications to support installation
sessions from Play Store. These notifications are used in current
task and will be used in next planned task to detect the case
when default app is not available after Arc start. There is yet
another idea to implement installation progress in App launcher.

TEST=Manually on device.
TEST=unit_tests + extended browser_tests.
