x11: implement set_override_redirect

[lunixbochs]

• Tested on all platforms changed
• Added an entry to the changelog module 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

implements window.set_override_redirect() for x11 so it can be updated after the window is created
(Note: I just ported this from my 0.30 branch to master without retesting and I'm not sure on the WindowExtX11 downcast)

You need to rebase though.

[lunixbochs]

I would greatly prefer to not keep rebasing the four PRs I've had outstanding for over a year. Last time you asked me to rebase, you did not merge or reply after I rebased: #4123 (comment)

Here, you suggested I have the maintainer do it at merge time: #3997 (comment)

I would prefer if a maintainer looks at my four outstanding PRs and performs the rebase at the time they merge.

https://github.com/talonvoice/winit/tree/0.30 has these changes recently rebased onto 0.30 if that makes the process easier.

[kchibisov]

Well, I can not rebase myself since I don't have permission, so I can not merge it.

If you can give permission maintainers to push to your things then I would have done all that myself and merged...

I would prefer if a maintainer looks at my four outstanding PRs and performs the rebase at the time they merge.

Well, then you should enable an option, since you disallow maintainers to do so.

I didn't explicitly disable maintainer edits, it looks like they're just not supported with cross-org PRs: https://github.com/orgs/community/discussions/5634

I granted you permissions directly on my fork.
