CLI: Add interactive session mode command open

This change adds a GNU Readline-based interactive mode to keepassxc-cli. If GNU Readline is not available, commands are just read from stdin with no editing or auto-complete support.

DatabaseCommand is modified to add the path to the current database to the arguments passed to executeWithDatabase. In this way, instances of DatabaseCommand do not have to prompt to re-open the database after each invocation, and existing command implementations do not have to be changed to support interactive mode.

This change also introduces a new way of handling commands between interactive and batch modes.

* Fixes #3224.
* Ran make format
