Buildable Overmap Machinery (#18974)

Sensors, IFF beacons, and thrusters can now be built with circuit
boards.
Ship sensors consoles will no longer throw an error if their sensors are
deleted or destroyed.
Thrusters and other unary atmos machines now take their initial dir from
the machine frame like other machines rather than requiring modification
of the circuit board item.
