probe: Infer position_endstop when using probe:z_virtual_offset
Don't require (or permit) the user to specify a stepper_z position_endstop when using the probe:z_virtual_offset mechanism. In that case the position_endstop should always equal the probe's z_offset - so no need to have the user specify it. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
