cb79b9dbf4cd06e17c8c65b36bf15c3ea2641de4 [mempool] Revert unbroadcast set to tracking just txid (Amiti Uttarwar)

Pull request description:

  Addresses some outstanding review comments from #18044

  - reverts unbroadcast txids to a set instead of a map (simpler, communicates intent better, takes less space, no efficiency advantages of map)
  - adds safety around two touchpoints (check for nullptr before dereferencing pointer, remove an inaccurate std::move operator)
  - removes some dead code

src/node/

The src/node/ directory contains code that needs to access node state (state in CChain, CBlockIndex, CCoinsView, CTxMemPool, and similar classes).

Code in src/node/ is meant to be segregated from code in src/wallet/ and src/qt/, to ensure wallet and GUI code changes don't interfere with node operation, to allow wallet and GUI code to run in separate processes, and to perhaps eventually allow wallet and GUI code to be maintained in separate source repositories.

As a rule of thumb, code in one of the src/node/, src/wallet/, or src/qt/ directories should avoid calling code in the other directories directly, and only invoke it indirectly through the more limited src/interfaces/ classes.

The src/node/ directory is a new directory introduced in #14978 and at the moment is sparsely populated. Eventually more substantial files like src/validation.cpp and src/txmempool.cpp might be moved there.
