gcode_macro: Use deepcopy() on get_status() results

Browse source 
If a get_status() method returns a mutable object (such as a list or
dict) then it would be possible for a gcode command template to
incorrectly alter the program's internal state.  Perform a deepcopy()
operation on all get_status() return results to avoid that.
