eb682c5700 util: Add ReadSettings and WriteSettings functions (Russell Yanofsky)

Pull request description:

  Persistent settings are used in followup PRs #15936 to unify gui settings between bitcoin-qt and bitcoind, and #15937 to add a load_on_startup flag to the loadwallet RPC and maintain a dynamic list of wallets that should be loaded on startup that also can be shared between bitcoind and bitcoin-qt.
