itersolve: Support setting the stepper position via a cartesian coordinate

Add support for an itersolve_set_position() function that sets a
stepper position from a cartesian coordinate.  This eliminates the
need for both the python and C code to be able to translate from a
cartesian coordinate to a stepper position.
