Bump winit to 0.30.0 and accesskit to 0.14.0

[AndriBaal]

• Closes Update to winit 0.30 #4437
• Closes Update accesskit_winit #4219
• Blocked by feat: Winit 0.30.0 rust-windowing/glutin#1675

Here is a summary of the changes I made:

• Bump accesskit to version 0.14.0
• Bump winit to 0.30.0
• Partially done the glow integration
• Roughly implemented accesskit
• Implemented winit / wgpu

Here is a summary of things that need to be done:

• Integration with glow (have to wait until glutin-winit updates to winit 0.30.0)
• Not all accesskit_winit::Event are being processed, temporarily I have marked them with todo!() (found in winit_integration.rs)
• Move from deprecated winit::EventLoop::run_on_demand
• Documentation and testing
• Code review

Hey, looks like we are no longer blocked by rust-windowing/glutin#1675 bcs rust-windowing/glutin#1678 got merged :3

[AndriBaal]

Thanks for the reminder. I managed to get the hello world example running on x11 with glutin.

Quick summary of my changes:

• Updated and implemented accesskit like mentioned here
• Updated glutin and glutin-winit to newest version
• Removed rwh5 since glutin now support rhw6
• Fixed compiling issues on x11

TODO:

• Move from deprecated event_loop.run_on_demand and event_loop.run
• Test accesskit (I have only copied from the mentioned comment and not tested it in depth by myself)
• Test on different plattforms (I only tested it on x11)
• Fix egui_glow pure_glowexample

I have tested the AccessKit integration on Windows and Linux/X11 and it seem to be fine. However I got the following warnings:

Compiling the hello_world example on macOS failed with these errors though:

Hope this helps.

Yes, the warnings are expected as I mentioned here: Move from deprecated event_loop.run_on_demand and event_loop.run. These methods are deprecated due to the new app API by winit 0.30. I believe that major changes need to be made to the core of eframe to support the new winit app API and I don't know if I'm familiar enough with egui to do such a refactor.

Thanks for testing on macOS. I think I fixed the errors, fell free to pull and try again :)

[DataTriny]

It now compiles on macOS. I've tested accessibility on this platform as well. Thanks!
