Change Details

> Add single sha256 call to CHashWriter > Add SHA256Uint256 helper functions > Refactor Get{Prevout,Sequence,Outputs}Hash to Get{Prevouts,Sequences,Outputs}SHA256. > > Several proposals (Taproot, MuHash, CTV) require access to the single > hash. This is a backport of core#19601 This backport was previously ignored because I assumed it was only needed for taproot. But it is also a dependency for other features, such as MuHash3072 (improving the performance of `gettxoutsetinfo`).
