Merge #12490: [Wallet] [RPC] Remove deprecated wallet rpc features from bitcoin_server

f7e9e70468 [rpc] Remove deprecated sigrawtransaction rpc method. (John Newbery)
90c834089a [RPC] Remove warning about wallet addresses in createmultisig() (John Newbery)
df905e390e [rpc] Remove deprecated validateaddress usage. (John Newbery)

Pull request description:

  The following rpc features were deprecated in V0.17:

  - `validateaddress` returning wallet information about an address
  - `signrawtransaction`

  This PR fully removes those features. It can be merged once V0.17 has been branched from master.
