Merge bitcoin/bitcoin#27724: build: disable boost multi index safe mode in debug mode

59c8944 build: disable boost multi index safe mode (willcl-ark)

Pull request description:

  Fixes #27586

  Disable boost multi index safe mode by default when configuring with
  --enable-debug.

  This option can cause transactions to take a long time to be accepted
  into the mempool under certain conditions; iterator destruction takes
  O(n) time vs O(1) as they are stored in a singly linked list. See
  27586 and the [boost docs](https://www.boost.org/doc/libs/1_58_0/boost/multi_index/detail/safe_mode.hpp) for more information.

  Re-enable it on the CI builds which previously had it enabled.

  Re-enable it on the msan fuzz task so that we have fuzz tasks testing
  with it enabled and disabled in this repo.
