Migrate /systemui/smartspace tests to bivalent.

Bivalent: runs both without a device and with a device.

Currently these tests require a device to run.

Updated these tests to bivalent, and added them to SystemUiRoboTests,
which run deviceless. Without the SystemUiRoboTests: prefix, the tests
run on a device.
