c46c18b788cb0862aafbb116fd37936cbed6a431 wallet: refactor GetClosestWalletFeature() (Jon Atack)

Pull request description:

  This follows up on #18836 and #20282 to fix and improve the as-yet unreleased `upgradewallet` feature and also implement review follow-up in https://github.com/bitcoin/bitcoin/pull/18836#discussion_r519328607.

  This PR fixes 4 upgradewallet issues:

  - this bug: https://github.com/bitcoin/bitcoin/pull/20403#discussion_r526063920
  - it returns nothing in the absence of an RPC error, which isn't reassuring for users
  - it returns the same thing both in the case of a successful upgrade and when no upgrade took place
  - the error message object is currently dead code

  This PR fixes the above and provides:

  ...user feedback to not silently return without upgrading
  ```
  {
    "wallet_name": "disable private keys",
    "previous_version": 169900,
    "current_version": 169900,
    "result": "Already at latest version. Wallet version unchanged."
  }
  ```
  ...better feedback after successfully upgrading
  ```
  {
    "wallet_name": "watch-only",
    "previous_version": 159900,
    "current_version": 169900,
    "result": "Wallet upgraded successfully from version 159900 to version 169900."
  }
  ```
  ...helpful error responses
  ```
  {
    "wallet_name": "blank",
    "previous_version": 169900,
    "current_version": 169900,
    "error": "Cannot downgrade wallet from version 169900 to version 159900. Wallet version unchanged."
  }
  {
    "wallet_name": "blank",
    "previous_version": 130000,
    "current_version": 130000,
    "error": "Cannot upgrade a non HD split wallet from version 130000 to version 169899 without upgrading to support pre-split keypool. Please use version 169900 or no version specified."
  }
  ```
  updated help:
  ```
  upgradewallet ( version )

    "previous_version" : n,    (numeric) Version of wallet before this operation
    "current_version" : n,     (numeric) Version of wallet after this operation
