[7648] Resolve problems with expected fall damage at near teleport. Author: VladimirMangos

Move near teleport landing code to WorldSession::HandleMoveTeleportAck.
    This make Player::TeleportTo code working in same way for both far/near teleports.
    Move mSemaphoreTeleport from WorldObject to Player and merge with DoNotMove (using 2 fields for far/near teleport flag).
    Skip movement packets until landing confirmation for near teleport from client.
