extruder: Support SYNC_STEPPER_TO_EXTRUDER on extruder objects

Browse source 
Refactor the extruder_stepper support so that it uses the
ExtruderStepper class defined in extruder.py.

Support the SYNC_STEPPER_TO_EXTRUDER command on steppers defined in
either extruder_stepper or extruder config sections.
