Merge #20365: wallettool: add parameter to create descriptors wallet

173cc9b7be335b5dd2cc1bb112dfa6ec5c13ec12 test: walettool create descriptors (Ivan Metlushko)
345e88eecf1b28607d5da3af38e19794a8a115ce wallettool: add param to create descriptors wallet (Ivan Metlushko)
6d3af3ab627096a824cb6a7ca1ebeddc7530361c wallettool: pass in DatabaseOptions into MakeWallet (Ivan Metlushko)

Pull request description:

  Rationale: expose and promote descriptor wallets in more places; make cli tool more consistent with `createwallet` rpc.

  Add `-descriptors` parameter which is off by default. When specified it will create a new descriptors wallet with sqlite backend, which is consistent with `createwallet` rpc.

  This PR is based on a suggestion from **ryanofsky** https://github.com/bitcoin/bitcoin/pull/19137#discussion_r516779603

  Example:
  ```
  $ ./src/bitcoin-wallet  -wallet=fewty -descriptors create
  Topping up keypool...
  Wallet info
  ===========
  Name: fewty
  Format: sqlite
  Descriptors: yes
  Encrypted: no
  HD (hd seed available): yes
  Keypool Size: 6000
  Transactions: 0
  Address Book: 0
  ```
  ```
  $ ./src/bitcoin-wallet  -wallet=fewty create
  Topping up keypool...
  Wallet info
  ===========
  Name: fewty
  Format: bdb
  Descriptors: no
  Encrypted: no
  HD (hd seed available): yes
  Keypool Size: 2000
  Transactions: 0
  Address Book: 0
  ```
