Pull request description:

  This implements an idea from sipa in https://github.com/bitcoin/bitcoin/issues/28722#issuecomment-2807026958 to allow `bitcoin-cli` to connect to the node via IPC instead of TCP, if the ENABLE_IPC cmake option is enabled and the node has been started with `-ipcbind`.

  This feature can be tested with:

  ```
  build/bin/bitcoin-node -regtest -ipcbind=unix -debug=ipc
  build/bin/bitcoin-cli -regtest -ipcconnect=unix -getinfo
  ```

  The -ipconnect parameter can also be omitted, since this change also makes `bitcoin-cli` prefer IPC over HTTP by default, and falling back to HTTP if an IPC connection can't be established.
