SC2: Content update (#5312)

Feature highlights:
- Adds many content to the SC2 game
- Allows custom mission order
- Adds race-swapped missions for build missions (except Epilogue and NCO)
- Allows War Council Nerfs (Protoss units can get pre - War Council State, alternative units get another custom nerf to match the power level of base units)
- Revamps Predator's upgrade tree (never was considered strategically important)
- Adds some units and upgrades
- Locked and excluded items can specify quantity
- Key mode (if opt-in, missions require keys to be unlocked on top of their regular regular requirements
- Victory caches - Victory locations can grant multiple items to the multiworld instead of one 
- The generator is more resilient for generator failures as it validates logic for item excludes
- Fixes the following issues:
