When creating a new spend, if coin outpoints are not provided,
then coins will be selected automatically.
This automatic selection is such that the transaction fee is
minimized, taking into account the cost of creating any
change output now and the cost of spending it in the future.
If change is added, it must reduce the transaction waste and
be above the dust threshold. This same policy is applied also
in the case of manual coin selection, replacing the previous
logic for determining the change amount. This ensures that
creating a spend with auto-selection and another with manual
selection using the same auto-selected coins will give the
same change amount.

This reverts commit 71056982636b408485ab24dab6628a555a6e7924, reversing
changes made to 03c37bd378f4f6bf11d90b224ed1db74b3596eaf.
This reverts PR #722. It turns out the Ledger Bitcoin app needs the
BIP32 derivation for all the keys in the Script, not only for the
spending path used. Therefore always create PSBT with all the BIP32
derivations. We'll add a way to prune them for talking to the Bitbox in
a future commit.

When creating a PSBT, only include the BIP32 derivations in each input
for the spending path this PSBT was created for.
This is to workaround Bitbox only providing a single signature per
input. Most likely other signing devices will have this behaviour too in
the future. See
https://github.com/wizardsardine/liana/pull/706#issuecomment-1744705808.
Multiple change indexes may be present in a spend
draft transaction and can be detected instead
in the response psbt with the bip32_derivation
outputs fields.
This is a new command dedicated to the recovery usecase. For now it's
dead simple: sweep all coins that are available through the recovery
path to a given address.
Since the Spend transaction command requires some parameters, this
implements the parameter-getting logic on the JSONRPC side as well.
This allows us to implement an end-to-end functional test of the
transaction flow using an external way to broadcast it. From the input
coins creation, to the Spend transaction broadcast.
