Support the Windows 11 I/O ring API

[teo-tsirpanis]

As noticed in #51985 (comment), Windows 11 will get a new I/O API similar to io_uring.

Since it's still in preview, documentation and details about it are scant. When more are released and if it is decided to support it in a future release, this issue will track it.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

The documentation is at https://learn.microsoft.com/en-us/windows/win32/api/ioringapi/ .

I would try implementing an sample locally for the usage of IORing in C# and measure some performance.

Are there already implemented some Win11+ only libraries in .NET? Is there a preprocessor variable for WINDOWS_11 and upwards?
Or does this need some runtime checks?

You would need a runtime check.
