Merge #12119: [wallet] use P2WPKH change output if any destination is P2WPKH or P2WSH
596c446 [wallet] use P2WPKH change output if any destination is P2WPKH or P2WSH (Sjors Provoost)
Pull request description:
If `-changetype` is not explicitly set, then regardless of `-addresstype`, the wallet will use a ~`bech32` change address~ `P2WPKH` change output if any destination is `P2WPKH` or `P2WSH`.
This seems more intuitive to me and more in line with the spirit of [BIP-69](https://github.com/bitcoin/bips/blob/master/bip-0069.mediawiki).
When combined with #11991 a QT user could opt to use `bech32` exclusively without having to figure out how to launch with `-changetype=bech32`, although so would #11937.
