Pull request description:
Following #17261, the way to sign transactions, PSBTs, and messages was to use `GetSigningProvider()` and get a `SigningProvider` containing the private keys. However this may not be feasible for future `ScriptPubKeyMan`s, such as for hardware wallets. Instead of exporting a `SigningProvider` containing private keys, we need to pass these things into the `ScriptPubKeyMan` (via `CWallet`) so that they can do whatever is needed internally to sign them. This is largely a refactor as the logic of processing transactions, PSBTs, and messages for is moved into `LegacyScriptPubKeyMan` and `CWallet` instead of being handled by the caller (e.g. `signrawtransaction`).
To help with this, I've refactored the 3(!) implementations of a `SignTransaction()` function into one generic one. This function will be called by `signrawtransactionwithkey` and `LegacyScriptPubKeyMan::SignTransaction()`. `CWallet::CreateTransaction()` is changed to call `CWallet::SignTransaction()` which in turn, calls `LegacyScriptPubKeyMan::SignTransaction()`. Other `ScriptPubKeyMan`s may implement `SignTransaction()` differently.
`FillPSBT()` is moved to be a member function of `CWallet` and the `psbtwallet.cpp/h` files removed. It is further split so that `CWallet` handles filling the UTXOs while the `ScriptPubKeyMan` handles adding keys, derivation paths, scripts, and signatures. In the end `LegacyScriptPubKeyMan::FillPSBT` still calls `SignPSBTInput`, but the `SigningProvider` is internal to `LegacyScriptPubKeyMan`. Other `ScriptPubKeyMan`s may do something different.
A new `SignMessage()` function is added to both `CWallet` and `ScriptPubKeyMan`. Instead of having the caller (i.e. `signmessage` or the sign message dialog) get the private key, hash the message, and sign, `ScriptPubKeyMan` will now handle that (`CWallet` passes through to the `ScriptPubKeyMan`s as it does for many functions). This signing code is thus consolidated into `LegacyScriptPubKeyMan::SignMessage()`, though other `ScriptPubKeyMan`s may implement it differently. Additionally, a `SigningError` enum is introduced for the different errors that we expect to see from `SignMessage()`.
Lastly, `GetSigningProvider()` is renamed to `GetPublicSigningProvider()`. It will now only provide pubkeys, key origins, and scripts. `LegacySigningProvider` has it's `GetKey` and `HaveKey` functions changed to only return false. Future implementations should return `HidingSigningProvider`s where private keys are hidden.
Other things like `dumpprivkey` and `dumpwallet` are not changed because they directly need and access the `LegacyScriptPubKeyMan` so are not relevant to future changes.

Not all ScriptPubKeyMans will be able to provide private keys,
but pubkeys and scripts should be. So only provide public-only
SigningProviders, i.e. ones that can help with Solving.
Instead of fetching a SigningProvider from ScriptPubKeyMan in order
to fill and sign the keys and scripts for a PSBT, just pass that
PSBT to a new FillPSBT function that does all that for us.

Pull request description:
A lot of places refer to `CWallet*`'s as `CWallet * const`, which translates to *"an immutable pointer to a mutable `CWallet` instance"*; this is
1. often not what the author meant, especially as a lot of these places do not at all modify the wallet object, and
2. confusing, as it tends to suggest that this is a proper way to refer to a constant `CWallet` instance.
This PR changes references to wallets to `const CWallet* const` whenever immutability is expected. This should result in no behavioral changes at all, and improved compile-time error checking.
Note from irc:
> <sipa> sounds good to me; this is the sort of change that as long as it compiles, the behavior shouldn't change
> <sipa> though in general it may lead to introducing automatic copying of objects sometimes (e.g. trying to std::move a const object will work, but generally result in a copy rather than an efficient move)

Pull request description:
In https://github.com/bitcoin/bitcoin/pull/13557#pullrequestreview-135905054 I recommended not including bip32 deriviation by default in PSBTs:
> _Bit of a privacy issue_: let's say person A and B are about to spend from a multisig address, sending everything to person A. Person A gives their address to person B, their wallet wallet creates a PSBT, but doesn't sign it. Wallet A then calls `walletprocesspsbt` which signs it and _spontaneously adds the master_fingerprint and bip32 path_. Same issue with `walletcreatefundedpsbt`.
>
> Adding `bip32_derivs` should probably be opt-in.
In practice I find this default quite annoying because I forget it and end up with a confused hardware wallet.
More importantly, in the multisig example I provided, it's actually essential for the other side to know the derivation details (in addition to an xpub). This allows them to check that change is going to an address you can still co-sign for (because the spending policy is unchanged except for an index).

These functions are used to mark/check if a key of our own has been used to spend (and only for avoid-reuse wallets), which has nothing to do with the destination/address itself.

Another small step to get rid of legacy addresses in the RPC help texts and by that encourage the use of bech32 addresses by default.
