Route the in-place toolchange tower entry through the skip-point gap

Browse Source 
On multi-tool printers without ramming the tool changes away from the
tower and the entry travel is the tcr's own positioning move, which went
straight across the printed wall. Append the avoid-perimeter path to the
change-filament gcode instead, so the head approaches around the tower
and enters through the wall opening (append_tcr parity).
