tracehints can't create vias

[seveibar]

Trace hints that are routed inside of Trace.ts don't create pcb_via soup elements

[homie-gg]

This might be a duplicate of: tracehints don't create pcb_trace_hint elements.

Here are some pull requests that might be helpful reference for this task:

• make optional
• Trace Hint Implementation (single layer)
• Fix Manual Trace Hints

[homie-gg]

This might have already been done via: Multilayer traces and vias, fixes traces routed inside Trace.ts are always routed on top layer.

[homie-gg]

This might have already been done via: fix multilayer routing for traces with trace hints.

[homie-gg]

This might have already been done via: support multilayer routing without hints, if footprint string is specified, move to component layer.

[homie-gg]

This might have already been done via: add vias for pcb trace routes.

[homie-gg]

This might have already been done via: Use last route point for end_pcb_port_id.

[homie-gg]

This might have already been done via: updated to circuit-json and added pcb_trace_id to via.
