Disallow bech32m addresses for legacy wallet things

We don't want the legacy wallet to ever have bech32m addresses so don't
allow importing them. This includes addmultisigaddress as that is a
legacy wallet only RPC

Additionally, bech32m multisigs are not available yet, so disallow them
in createmultisig.
