Bevy 0.11.0-dev compatibility

[coreh]

Hey 👋

I needed picking for a project targeting the latest current main bevy branch, (v0.11.0-dev) so I've updated this crate (and also bevy_mod_raycast) to work under it. Here are the breaking changes I had to account for:

• Removal of base sets
• Changes to .add_systems()
• Y coordinate of cursor position is no longer flipped

It's likely there will be more breaking changes before the 0.11.0 release; I'll try to keep this PR up-to-date.

To Do

• Double check all schedule assignments are indeed correct, I tried my best but there were a lot of them, I might have gotten one or two switched up by mistake. All demos (except alternate backends? see below) seem to be working correctly, though.
• Get backend_egui working (Might need upstream update?)
• Get backend_rapier3d working (Might need upstream update?)

I refreshed a bit the PR there: coreh#1

We should also remove the Y flipping for touch events here.
