Bug: 113028175
Bug: 134430124
Test: Build and flash taimen with the matching bootloader change. Toggle
dark mode in Settings. Check serial log regarding the start of
vendor.theme_{set,clear} services. Also read the value via `dd bs=1
skip=2048 if=/dev/block/sda5 count=32 | xxd` to confirm the change.
Test: Trigger a factory reset via Settings. Check the value in /misc
after the reset.
