Merge pull request #27242 from mshabunin:fix-uwp-build 
Looks like UWP builds were broken on 5.x:
```

```

Notes:

- Pipeline passes even though there are errors in the build
- I decided to remove _highgui_ WinRT backend, because it uses C-API which is has been removed in 5.x. I believe nobody uses it anyway.
- Change in anneal library is caused by the issue in WinAPI header - it does not declare two functions for UWP, even though documentation states compatibility. See also https://github.com/openssl/openssl/pull/18311
