refactor: name GUID type and LFG role constants, add why-comments

Browse source 
- world_packets: name kGuidTypeMask/kGuidTypePet/kGuidTypeVehicle
  for chat receiver GUID type detection, with why-comment explaining
  WoW's bits-48-63 entity type encoding and 0xF0FF mask purpose
- lua_engine: name kRoleTank/kRoleHealer/kRoleDamager (0x02/0x04/0x08)
  for WotLK LFG role bitmask, add context on Leader bit (0x01) and
  source packets (SMSG_GROUP_LIST / SMSG_LFG_ROLE_CHECK_UPDATE)
