Add update_verifier for A/B OTA update.

update_verifier checks the integrity of the updated system and vendor
partitions on the first boot post an A/B OTA update. It marks the
current slot as having booted successfully if it passes the verification.

This CL doesn't perform any actual verification work which will be
addressed in follow-up CLs.
