AP_BoardConfig: expose BRD_SAFETYENABLE on all boards 

default BRD_SAFETYENABLE to 0 on boards with no safety switch, which
gives us the same behaviour as before, but users can choose to enable
the safety

this fixes two problems:

  - CAN servos and ESCs work on boards with no safety switch
    (eg. MatekH743 with CAN)

  - during startup we could get spurious outputs before out aircraft
    type is setup

When set to zero the safety switch will start in the unsafe state (solid) at startup. Note that if a safety switch is fitted the user can still control the safety state after startup using the switch. The safety state can also be controlled in software using a MAVLink message.
