add ability to call variable_user_park_move_macro on restore position.

when restoring the from parked postion the same macro is called but passed a RESTORE=1 parameter, along with co-ordinates to restore to YOUR_MOVE_MACRO RESTORE=1 X=<x_coord> Y=<y_coord> F=<speed>

example of macro

[gcode_macro _MMU_USER_PARK]
description: always move to X74 first to clear brush then move in the Y direction, followed by the X direction
gcode:
  {% if params.RESTORE == 1 %}
    G1 X74 F{params.F}
    G1 Y{params.Y} F{params.F}
    G1 X{params.X} F{params.F}
  {% else %}
    G1 X74 F{params.F}
    G1 Y{params.Y} F{params.F}
    G1 X{params.X} F{params.F}
  {% endif %}
