[dalkia]

What does this PR change?

Stops the in-world-camera from spawning when using the chat or in the loading screen

How to test the changes?

1. Launch the explorer with in world camera feature on
2. Select the chat. Press C. The in world camera should not open
3. Deselect the chat. Press C. The world camera should open
4. Teleport anywhere. While loading screen is on, press C. The world camera should not open
5. When arriving to destination, press C. The camera should open

Try the regular input blocks as well (Shortcuts, Movement, Camera, FreeCamera, Emotes and EmotesWheel). They should all behave the same

🔴 I could only test on Windows as Mac failed. On Windows, I wasn't able to open the camera using the C shortcut, only by using the sidebar camera icon. All other shortcuts (B, P, I, U, etc.) worked fine.
