Add maximum timestamp to the payload.

Added a new field max_timestamp in the protobuf, from now on
update_engine will reject any payload without this field.
If the OS build timestamp is newer than the max_timestamp, the payload
will also be rejected to prevent downgrade.

Bug: 36232423
Test: update_engine_unittests
