Merge bitcoin/bitcoin#25737: rpc: treat univalue type check error as RPC_TYPE_ERROR, not RPC_MISC_ERROR

e68d380797 rpc: remove unneeded RPCTypeCheckArgument checks (furszy)
55566630c6 rpc: treat univalue type check error as RPC_TYPE_ERROR, not RPC_MISC_ERROR (furszy)

Pull request description:

  Same rationale as #26039, tackling another angle of the problem.

  #### Context
  We have the same univalue type error checking code spread/duplicated few times:
  `RPCTypeCheckObj`, `RPCTypeCheckArgument`, `UniValue::checkType`.

  In the first two functions, we are properly returning an `RPC_TYPE_ERROR` while in `UniValue::checkType`
  we are throwing an `std::runtime_error` which is caught by the RPC server request handler, who invalidly
  treats it as `RPC_MISC_ERROR` (which is a generic error return code that provides no information to the user).

  #### Proposed Changes

  Throw a custom exception from `Univalue::checkType` (instead of a plain
  `std::runtime_error`) and catch it on the RPC server request handler.

  So we properly return `RPC_TYPE_ERROR` (-3) on every arg type error and
  not the general `RPC_MISC_ERROR` (-1).

  This will allow us to remove all the `RPCTypeCheckArgument` calls. As them are redundant since #25629.
