Merge #18531: rpc: remove deprecated CRPCCommand constructor

faaf9c58e4aa809019d4ca12747dd47411988e37 remove CRPCCommand constructor that takes rpcfn_type function pointer (MarcoFalke)
fa19bb2cd8c575593583138a84e6bb3444d6196d remove dead rpc code (MarcoFalke)

Pull request description:

  Remove the CRPCCommand arguments, now that they are asserted to be equal and thus redundant

  ### Future work

  > Here or follow up, makes sense to also assert type of returned UniValue?

  Sure, but let's not get ahead of ourselves. I am going to submit any further works as follow-ups, including:

  * Removing all python regex linters on the args, now that RPCMan can be used to generate any output, including the cli.cpp table
  * Auto-formatting and sanity checking the RPCExamples with RPCMan
  * Checking passed-in json in self-check. Removing redundant checks
  * Checking returned json against documentation to avoid regressions or false documentation
  * Compile the RPC documentation at compile-time to ensure it doesn't change at runtime and is completely static

  ### Bugs found

  * The assert identified issue #18607
  * The changes itself fixed bug #19250
