Merge bitcoin/bitcoin#27349: test: use address_to_scriptpubkey instead of RPC call

e47ce42f67 refactor: use address_to_scriptpubkey to retrieve addresses scriptpubkey (ismaelsadeeq)
4142d19d74 refactor: move address_to_scriptpubkey to address.py (ismaelsadeeq)

Pull request description:

  PR #27269 enables the function address_to_scriptpubkey() to decode all address types and return their corresponding scriptpubkeys. As a result, there is no longer any need to call getaddressinfo or validateaddress RPCs in order to retrieve an address scriptpubkey, as explained in the comments on this pull request (see https://github.com/bitcoin/bitcoin/pull/27269#pullrequestreview-1353681933 and https://github.com/bitcoin/bitcoin/pull/27269#issuecomment-1481016118).

  Instead of using RPC calls, this update replaces the process of obtaining an address scriptPubkey with the address_to_scriptpubkey method, resulting in improved performance for functional tests.
