Merge bitcoin/bitcoin#23480: Add rawtr() descriptor for P2TR with specified (tweaked) output key
544b4332f0e122167bdb94dc963405422faa30cb Add wallet tests for spending rawtr() (Pieter Wuille)

8d9670ccb756592bddb2a269bf5078d62658537b Add rawtr() descriptor for P2TR with unknown tweak (Pieter Wuille)
Pull request description:
It may be useful to be able to represent P2TR outputs in descriptors whose script tree and/or internal key aren't known. This PR does that, by adding a `rawtr(KEY)` descriptor, where the KEY represents the output key directly. If the private key corresponding to that output key is known, it also permits signing with it.
I'm not convinced this is desirable, but presumably "tr(KEY)" sounds more intended for direct use than "rawtr(KEY)".
