feat(Blenvy): unified & cleaned up node trees handling for materials/geonodes

* manual tests are coherent, and allow for very fine grained changed detection, yeah !!
 * overhauled generic_fields_hasher_evolved a bit
 * fixed/ resolved issues with parameters handling for materials vs modifiers
 * related minor tweaks & fixes
