275e9390e1 mining, refactor: add m_mempool.cs thread safety lock assertions (Jon Atack)

Pull request description:

  in src/node/miner to

  - BlockAssembler::addPackageTxs()
  - BlockAssembler::SkipMapTxEntry()
  - BlockAssembler::UpdatePackagesForAdded()

  These functions have thread safety lock annotations in their declarations but are missing the corresponding run-time lock assertions in their definitions.

  Per doc/developer-notes.md: "Combine annotations in function declarations with run-time asserts in function definitions."
