Add QS tile for Night Display when first used

Bug: 30994985
Test: runtest systemui, and manual - verify that the quick settings
panel does not have a Night Display quick settings tile, then turn
Night Display on and verify that the tile has appeared. Multiuser
does NOT work and is tracked separately.
