796b020c37 wallet: add taproot support to external signer (Sjors Provoost)
Pull request description:
Builds on #22558 (merged on 2022-06-28).
[HWI 2.1.0](https://github.com/bitcoin-core/HWI/releases/tag/2.1.0) or newer is required to import and use taproot descriptors. Older versions will work, but won't import a taproot descriptor.
Tested with HWI 2.1.1:
* Trezor T (firmware v2.5.1) on Signet: signs, change detection works
* Ledger Nano S (firmware 2.1.0, Bitcoin app 2.0.6): signs, change detection works
Only the most basic `tr(key)` descriptor is supported, script path spending is completely untested (if it works at all).

Quoting ryanofsky: "util can be the library for things included in the kernel
which the kernel can depend on, and common can be the library for other code
that needs to be shared internally, but should not be part of the kernel or
shared externally."
This commit moves the ExternalSigner class and RPC methods out of the wallet module.
The enumeratesigners RPC can be used without a wallet since #21417.
With additional modifications external signers could be used without a wallet in general, e.g. via signrawtransaction.
The signerdisplayaddress RPC is ranamed to walletdisplayaddress because it requires wallet context.
A future displayaddress RPC call without wallet context could take a descriptor argument.
This commit fixes a rpc_help.py failure when configured with --disable-wallet.
