test: refactor: return TaprootInfo from P2TR address creation routine

Browse source 
Rather than only returning the internal key from the P2TR anyone-can-spend
address creation routine, provide the whole TaprootInfo object, which in turn
contains a dictionary of TaprootLeafInfo object for named leaves.

This data is used in MiniWallet for the default ADDRESS_OP_TRUE mode, in order
to deduplicate the witness script and leaf version of the control block.
