[8339] Improved storing/restoring BG entry point

    * Introduced new table character_battleground_data
    * Entry point is now stored on BG enter event not join event
    * Entry point for dungeons is now correctly set to nearest graveyard
      (this prevent well known assert in GetInstance because of porting to already destroyed instance)
    * Teleporting from BG correctly restore mount state
    * Teleporting from BG correctly restore taxi flight
      (in multipath flight you will end up in nearest transition point on the route)
