Merge #13441: Prevent shared conf files from failing with different available options in different binaries

c2dfbb4a97 Add unavailable options to hidden options category (Andrew Chow)

Pull request description:

  From IRC:

  ```
  <ossifrage> FYI, bitcoin-qt from the head I built today won't start if you have "daemon=0" in the config file, so you can't use the same config for either bitcoind or bitcoin-qt
  <ossifrage> Seems like bitcoin-qt should ignore this option?
  <provoostenator> ossifrage: probably caused by 13112. Another problem is disablewallet=1 will prevent a launch if you compile bitcoind without wallet. It probably needs to be relaxed slightly.
  ```

  Adds all of the options that are unavailable due to compiling options to the hidden category so that shared config files do not break with the alternative binaries.
