Merge #16798: Refactor rawtransaction_util's SignTransaction to separate prevtx parsing
39034f1ee628dae0bc9da5b1b30b8a424e66d968 Refactor rawtransaction_util's SignTransaction to have previous tx parsing be separate (Andrew Chow)

Pull request description:

  Currently the `SignTransaction` function has to handle both the actual signing and parsing of previous transaction data. This PR splits it so that `SignTransaction` only handles the signing itself and adds a `ParsePrevouts` function which handles parsing the prevtx information.

  This allows for `SignTransaction` to just take any `SigningProvider`.

  Split from #16341
