script/sign: Miniscript support in Tapscript

Browse Source 
We make the Satisfier a base in which to store the common methods
between the Tapscript and P2WSH satisfier, and from which they both
inherit.

A field is added to SignatureData to be able to satisfy pkh() under
Tapscript context (to get the pubkey hash preimage) without wallet data.
For instance in `finalizepsbt` RPC. See also the next commits for a
functional test that exercises this.
