Merge bitcoin/bitcoin#32139: test: remove strict restrictions on rpc_deprecated test

459807d test: remove strict restrictions on rpc_deprecated (Pol Espinasa)

Pull request description:

  Removed the wallet restrictions for `rpc_deprecated.py` and added specific test case for the current deprecated rpc.
  `skip_test_if_missing_module` will skip the whole test when the wallet is missing, even if a part of the test is non-wallet related. This PR ensures that other tests not related to wallet can be ran and only this specific test will be skipped if there's no wallet
