bbe82c116e Fix #29767, set m_synced = true after Commit() (nanlour)

Pull request description:

  I think this problem https://github.com/bitcoin/bitcoin/issues/29767#issue-2216373048 is because of
  in BaseIndex::Sync
  61de64df67/src/index/base.cpp (L163-L168)
  Setup m_synced = true; before Commit();
  So this may cause a race condition window to BaseIndex::BlockConnected
  61de64df67/src/index/base.cpp (L271-L274)
  So i try to fix it with move m_synced = true after Commit().
  Also see comment of Sync():
  61de64df67/src/index/base.h (L151-L156)
  I am a newcomer interested in Bitcoin, trying to become a member of the Bitcoin Core development team. Please give me some feedback if you could, as I may be doing something wrong. Thank you!
