Merge #15937: Add loadwallet and createwallet load_on_startup options

642ad31b41 Add loadwallet and createwallet RPC load_on_startup options (Russell Yanofsky)

Pull request description:

  This maintains a persistent list of wallets stored in settings that will automatically be loaded on startup. Being able to load a wallet automatically on startup will be more useful in the GUI, but it's reasonable to expose this feature by RPC as well.
