[OC2] Enabled DLC Option (#1688)

- New OC2 option `DLCOptionSet`, which is a list of DLCs whose levels should or shouldn't be used for entrance randomizer (and mention in documentation). By default, DLC owners now need to enable DLCs in weighted settings.
- Throw user-friendly exceptions when contradictory settings are enabled
- Slightly relax generation requirements for sphere 1/2 level permutations
- Write entrance randomizer info in spoiler log
- Skip adding "Dark Green Ramp" to item pool if Kevin Levels are disabled
