Wargear associations for other units

[ThePants999]

Similar to #1424, it would be awesome to get a general pass through the data of using the new "association" system for units where there's a wargear option that needs to go on a specific model.

Some specific examples that come to mind:

• [ ] Space Marines - Intercessor Squad - Astartes Grenade Launcher
• [x] Space Marines - Infiltrator Squad - Helix Gauntlet & Infiltrator Comms Array
• [x] Space Marines - Incursor Squad - Haywire Mine
• [x] Chaos Daemons - various - Daemonic icons & Instruments of Chaos
• [x] Leagues of Votann - Hearthkyn Warriors - comms array, medipack, pan spectral scanner
• [ ] Drukhari - Reavers - Cluster caltrops & grav talon
• [x] Adepta Sororitas - Mortifiers - Anchorite Sarcophagus
