X2D Support (#13388)

# Description

Adresses #13294 

- Adds the X2D printer definition, machine presets, process presets,
filament presets, BBL profile index entries, CLI config entries,
filament blacklist updates, and printer/load/calibration/cover assets.
- Updates dual-nozzle handling to use configured toolhead labels and
match Bambu X2D hotend placeholders.
- Adds X2D-specific wipe tower cooling placeholder support and 3MF
filament/nozzle change sequence metadata import/export plumbing.

# Note

I own a P2S and an X2D. That's all. I frankly have no idea if my changes
cause regression on other printers, and have no capability to test. I
know that for my X2D, which runs an AMS, .2mm nozzles, SuperTack, and in
LAN mode, this has been working without issue.
