Changes to drones and z-macros (#7068)

Turns the z-level restriction procs into macros
Changes z-level restrictions to use the macros
Use contact_levels for announcements (instead of player_levels)
Restricts the teleporter to station_levels instead of player_levels
Restricts AI tracking to station_levels instead of player_levels
Mechs only get tracking beacons if they are on station_levels (instead of player_levels)
Construction Drones gib if they enter a station level
Mining Drones gib if they leave the station levels
Removes the mining equipment vendor from the scrapheap
