bugfix, cleanup: keep both is_ambient_pressure_close_to_surface in sync
The CPU1 firmware used 40cm of water pressure, and the RTE used 1m of
water pressure to detect between diving and surface state. This is
simply wrong, and can lead to small, rounding like, errors.
Use 1m water pressure as "official" depth things count as diving.
