Added HP/SP bonus from VIT/INT equips (#6914)

- Fixes #6911
- Each VIT on an equipment gives an additional +1 MaxHP
- Each INT on an equipment gives an additional +1 MaxSP
- Bonus is applied before % equip bonus
- Only applies for VIT/INT bonus directly on an equipment, but not for cards
- Replaced some hard-coded values with constants

Special thanks to @aleos89 and @secretdataz
