Try to solve a script using the Miniscript satisfier if the legacy solver fails under P2WSH context. Only solve public key and public key hash challenges for now. We don't entirely replace the raw solver and especially rule out trying to solve CHECKMULTISIG-based multisigs with the Miniscript satisfier since some features, such as the transaction input combiner, rely on the specific behaviour of the former.
