[7250] Use bg type ids enum insted raw values and catch some bugs in result for fixing.

* Replace max bg type checks by DBC valid index check
    * Use in functions and fields BattlegroundTypeId type instead uint32
    * Fixed wrong use bg queue ids instead bg type ids in queue update/remove function calls.
      Many bg have same raw values for type id and queue id but some can be affected by this bug:
      BATTLEGROUND_EY, BATTLEGROUND_SA, and all areans (with small arena/team size exceptions)
    * Move Battlemaster to bg type ids map fron ObjectMgr to BatteleGroundMgr.
    * Remobe redundent for header itself includes for BG headers.
    * Use Auction location enum instead raw valus.
