Respect node archetypes in autocompletion sorting

[HolonProduction]

I mainly used 2d before, but when trying to do some 3d prototypes I encountered the following annoyance with autocompletion: When completing types (e.g. for type hints, or to create new nodes) autocompletion is hard to use, since all types that exist in 2d and 3d start the same, both variants will match the completion filter. After that they will be sorted alphabetically, thus putting 2d before 3d. This requires either using arrow keys to submit the correct option, or just typing till the 3 (at this point I can type the d myself).

This could be improved by introducing node archetypes (2D, 3D, Control) as sorting parameter. The prioritized archetype would be determined by what the current script inherits. This sorting characteristic would take priority over alphabetical sorting, but locality sorting would take priority over it.

E.g.:

extends CharacterBody2D

var a: Spri... # would suggest [Sprite2D, Sprite3D]

extends CharacterBody3D

var a: Spri... # would suggest [Sprite3D, Sprite2D]
