Upgrade winit 0.29.2 → 0.30.0

[ErichDonGubler]

• Tested on all platforms changed
• Added an entry to CHANGELOG.md if knowledge of this change could be valuable to users
• Updated documentation to reflect any user-facing changes, including notes of platform-specific behavior
• Created or updated an example program if it would help users understand this functionality: I've updated examples, which I think might be sufficient?

Resolves #1674.

[MarijnS95]

The changes in glutin-winit's lib.rs look identical to #1675 minus some GlutinEventLoop trait to support the older EventLoop as argument to create_display().

Both PRs are refactoring the examples in a completely different way though, and I lean towards what you're doing here by loosing less code and maintaining more of the original architecture. But it remains hard to review both PRs as they (inevitably) move a lot of code around in the diff.

[ErichDonGubler]

@MarijnS95: I strongly recommend going through these changes commit-by-commit, rather than looking through the overall diff. I've striven to make each as small as possible.

This PR examples look better indeed, do you want to maybe merge your PR against mine? So mine goes with your examples

Sounds good? :-)

[MarijnS95]

@ErichDonGubler since you already expressed that you didn't expect this PR to get merged in favour of the other one, I didn't give this PR (nor the other one) more than a quick scroll-through.

Since your PR history is nice and readable, I propose to integrate that in one of the two branches.

[marc2332]

@ErichDonGubler Do you want me to just copy your examples straight into my PR or do you want to maybe rebase this PR on mine with my core changes and your examples so we can merge it into mine?

[ErichDonGubler]

@marc2332: I'll leave the choice up to you whether you want to force-push this branch's history onto yours at #1675, or just abandon it and get a fresh round of @MarijnS95's feedback here. I'm willing to handle feedback if it's left open here, in case that helps. 🙂

I've Incorporated all the changes from #1675 and applied some minor style/doc fixes.

Not sure why you did that, I already had his changes in my PR 🤔
