Merge bitcoin/bitcoin#23712: test: interface_bitcoin_cli.py: check specified wallet type availability

b57bf25 test: interface_bitcoin_cli.py: check specified wallet type availability (Sebastian Falbesoner)

Pull request description:

  Currently the test `interface_bitcoin_cli.py` performs the wallet-relevant parts if _any_ wallet type support is compiled in, independently of
  whether the test is run with legacy or descriptor wallet specified. This leads to a failure if the test is started with the `--legacy-wallet` parameter, but bitcoind is compiled without BDB support, see e.g
   bitcoin/bitcoin#23686 (comment)

  Fix this by checking if the specified wallet type (BDB for legacy wallet, SQLite for descriptor wallet) is available.

  Should further pave the way for #23682.
