UI state is not saved correctly if not using the internal Quit menu item

### Describe the bug

Running macOS, if I use Cmd+Q, the OS menu bar "Quit" item or any system way tell PCSX-Redux to exit, then all my currently opened windows won't be remembered at next launch. If I want to avoid the issue, I must click the internal ImGui menu item in the main window.

### Expected behavior

The GUI state should be saved regardless of the way which is used to exit the app. Especially in a PSX development scenario where PCSX has to be started a lot and where it's easier to quit via a keyboard shortcut.

### Steps to reproduce the bug

1. Start PCSX
2. Open, e.g. the CPU registers window
3. Hit Cmd+Q
4. Re-start PCSX
5. CPU registers window does not re-open
6. Open CPU registers window
7. Click the internal "Quit" menu item in the main window
8. Re-start PCSX
9. The CPU registers window re-opens
