Fix stringing between the model and the wipe tower (#15038)

Browse Source 
# Description

On multi-tool printers using the type 2 wipe tower, the travel to the
tower ignored the configured Z hop type and always used a plain vertical
hop, so the nozzle rose in place over the part and oozed instead of
lifting away with the travel. It now follows the filament's Z hop
setting, matching what the type 1 tower already does.
Only toolchange travels to a type 2 tower change. Normal Lift and z_hop
= 0 are unaffected, and no extrusion moves change in any mode.
