Qt: Skip emulator-specific things on startup if starting in manager mode:

- Don't try to read 86box.cfg;
- Don't initialize subsystems that aren't used in manager mode;
- Ignore `-I` or `-X` command-line options;
- Don't block keyboard navigation and mnemonics in menus;
- Don't perform UUID/WinBox/cpu_override checks.
