feat: upgrade to Bevy 0.17

[NoxTav]

Examples are working, egui is updated too

Thanks.

I did all this a long time ago (when Bevy 0.17 got released) but the full_egui example was not detecting correctly when egui was using the input (a bug in egui_dock apparently). Since then I had very litlle free time, but I will try to look at it.

Is the egui_full demo working correctly now?

bevy_egui have now a functionally to check if egui is using the input that can replace our implementation.

@thmxv Yes, I fixed the egui_full demo

@NoxTav Thanks, I had time to test and start a review yesterday. The egui_full demo is much better than during my first port. But it is still possible to start manipulating the camera by clicking on the toolbar buttons. But this is possibly not an issue coming from the example code but coming from a dependency.

Idealy the bevy_egui API provided to check if egui wants the input would be used and the way provided by us would be removed, but this can be done later separately.
