Add logging for Smart Space on Dream surface.

Bug: 227613246
Fix: 227613246
Test: manually on device - SS events logged same as for lockscreen.
Note: clicks are logged for reminder card but not for weather card,
which is the same behavior as for lockscreen.
Test: atest DreamSmartspaceControllerTest
