gui: Partially revert #10244 gArgs and Params changes

Change gui code to use gArgs, Params() functions directly instead of going
through interfaces::Node.

Remotely accessing bitcoin-node ArgsManager from bitcoin-gui works fine in
https://github.com/bitcoin/bitcoin/pull/10102, when bitcoin-gui spawns a new
bitcoin-node process and controls its startup, but for bitcoin-gui to support
-ipcconnect option in https://github.com/bitcoin/bitcoin/pull/19461 and connect
to an existing bitcoin-node process, it needs ability to parse arguments itself
before connecting out.

This change also simplifies https://github.com/bitcoin/bitcoin/pull/10102 a
bit, by making the bitcoin-gui -> bitcoin-node startup sequence more similar to
the bitcoin-node -> bitcoin-wallet startup sequence where the parent process
parses arguments and passes them to the child process instead of the parent
process using the child process to parse arguments.
