Modifier setting to control order of line type extruded to help mitigate benchy hull line and surface sheen differences

The idea was mentioned in https://help.prusa3d.com/article/the-benchy-hull-line_124745, where the deck perimeters were printed first and then the hull perimeters were printed. The Prusa devs had to reorder the gcode manually to fix the issue though.

So, what if we could set a modifier setting to control the order of line types being printed? I think this solution would have to depend on an improvement to intra-layer order to support part orders (which I hope also includes modifiers) that @Noisyfox mentioned in their implementation of intra-layer order (#3685).

Imagine, printing internal bridging, internal solid infill, or top surface first, then walls or any other line. The feature could help mitigate the difference in surface sheen caused by layer time differences.

As part of the solution to prevent a benchy hull line, the model may need to have a gap added to prevent the internal bridging, internal solid infill, or top surface from touching the walls. This can be accomplished by adding a negative modifier of a mesh. I've been able to create a negative modifier as part of my investigation to prevent the benchy hull line in Gridfinity bins that are generated with gridfinity-rebuilt-openscad.

To reiterate, the idea is to have a modifier be able to control the order of line types being printed.
