Display smartspace in lockscreen preview

Bug: b/271338533
Test: manual - smartspace shows up in proper screen location on landscape and portrait accross various devices
Test: manual - smartspace has correct alpha when selecting custom lockscreen shortcuts
Test: manual - smartspace can hide and show when requested to do so
Test: manual - after clock is set up, the smartspace hides or shows based on whether or not the clock has date or weather in it
