Adjust weapon pool build sorting to include alt kits/skins

[Sendouc]

• Include variants (alt skins, alt kits) in the sorting
• If the weapon pool contains a variant, sort that first

examples

Weapon pool = Luna Blaster, Splat Roller Currently sorts first Luna then Splat Roller Should be = Luna, Luna Neo, Roller, Krak-on roller, order replica

Weapon pool = Luna Blaster Neo, Luna Blaster, Splat Roller Currently sorts first Luna Blaster Neo then Luna then Splat Roller Should be = Luna Neo, Luna, Roller, Krak-on roller, order replica

It would be also nice to include unit tests
