Replace GT, Ganon vuln crystal checks, ped check with new system

InvincibleGanon 0x18003E -> GanonVulnerableMode 0x1801A8-0x1801A9
NumberOfCrystalsRequiredForTower 0x18005E -> GanonsTowerOpenTarget 0x18019A-0x18019B
NumberOfCrystalsRequiredForGanon 0x18005F -> GanonVulnerableTarget 0x1801A6-0x1801A7
Various fixes
Moved CrystalCounter to word length space $7EF471 -> $7EF476
