PP-521: Fix resolve logic for adhesion_type

PP-512 Fix resolve logic for adhesion_type
Pick the most "sticky" option of all the enabled extruders for adhesion_type

Problem

Currently, the resolve function for adhesion_type is extruderValue(adhesion_extruder_nr, 'adhesion_type'). But when using dual extrusion, Cura makes the brim from multiple materials, depending on what material that piece of brim touches.

For example with (1) PVA and (2) PPS-CF on a Factor 4, the current logic is that the global adhesion_extruder_nr defaults to 1 (left), and so it uses the adhesion_type value of the PVA, which doesn’t have any set, so defaults to the global skirt, even though the PPS-CF wants brim.

Solution

Make the resolve of adhesion_type a function that picks the first option from the list ['raft', 'brim', 'skirt', 'none'] that any of the used extruders selects.

"resolve": "min(extruderValues('adhesion_type'), key=lambda v: ('raft', 'brim', 'skirt', 'none').index(v))"

In this screenshot, left is the current/old profile, and right is with the new resolve function where Cura correctly picks up the brim preference of the PPS-CF.

That is really smart 👍
