Merge #20226: wallet, rpc: add listdescriptors command

647b81b70938dc4dbcf32399c56f78be395c721a wallet, rpc: add listdescriptors command (Ivan Metlushko)

Pull request description:

  Looking for concept ACKs

  **Rationale**: allow users to inspect the contents of their newly created descriptor wallets.

  Currently the command only returns xpubs which is not very useful in itself, but there are multiples ways to extend it:
   * add an option to export xprv
   * with #19136 it'll be possible to return normalised descriptors suitable for a watch-only purposes

  The output is compatible with `importdescriptors` command so it could be easily used for backup/recover purposes.

  **Output example:**
  ```json
  [
    {
      "desc": "wpkh(tpubD6NzVbkrYhZ4WW6E2ZETFyNfq2hfF23SKxqSGFvUpPAY58jmmuBybwqwFihAyQPk9KnwTt5516NDZRJ7k5QPeKjy7wuVd5WvXNxwwAs5tUD/*)#nhavpr5h",
      "timestamp": 1296688602,
      "active": false,
      "range": [

      "next": 0
    }
  ]
  ```
