Bug: 113028175
Bug: 134157796
Test: Build and flash walleye with the matching bootloader change.
Check serial log regarding the start of vendor.darkboot and
vendor.darkboot_clear services when toggling dark theme in
Settings. Also read the value via `dd bs=1 skip=14408
if=/dev/block/sdd1 count=32 | xxd` to confirm the change.
Test: Trigger a factory reset via Settings. Check the value in /misc
after the reset.
