Merge #16377: [rpc] don't automatically append inputs in walletcreatefundedpsbt

e5327f947c [rpc] fundrawtransaction: add_inputs option to control automatic input adding (Sjors Provoost)
79804fe24b [rpc] walletcreatefundedpsbt: don't automatically append inputs (Sjors Provoost)

Pull request description:

  When the user doesn't specificy inputs, it makes sense to automatically select them. But when the user does specify inputs, `walletcreatefundedpsbt` now fails if the amount is insufficient, unless `addInputs` is set to `true`.

  Similarly for `fundrawtransaction` if the original transaction already specified inputs, we only add more if `addInputs` is set to `true`.

  This protects against fat finger mistakes in the amount or fee rate (see also #16257). The behavior is also more similar to GUI coin selection.
