a2a92317ad rpc: Add warning to user about newkeypool command (Samuel Dobson)
Pull request description:
This PR prevents `newkeypool` from being run on non-HD wallets, because this would require a new backup every time, so it isn't very safe.
David Harding also suggested [here](https://github.com/bitcoin/bitcoin/pull/23093#issuecomment-945350003) that the RPC help text should include a warning to the users about the interaction between newkeypool.

Pull request description:
Fixes #21368
Currently, if there are any uncompressed keys when calling `AddAndGetMultisigDestination`, it will just default to a legacy address regardless of the chosen `address_type`. Rather than keeping this silent behaviour which may be confusing to users, we explicitly add a `warnings` field which will warn the user why their address format is different.
