Move UFOGen to research projects

[ParagEkbote]

What does this PR do?

As discussed previously, I have moved the UFOGen scheduler and the code shared by its co-authors to examples/research projects.

I have also followed the same approach that was talked about in #10046. The implementation added has been kept simplistic to avoid confusion as well. Please let me know if any further corrections are needed and I will make the necessary changes.

Fixes #10162 and closes #6133

Not sure research projects is the right place for a clone of an entire repo? Looks like the scheduler is the main thing and that was already added in community scripts.

The issue is that after the release of the UFOGen repo, the authors didn't publicly release a trained model based on the paper and it gets quite difficult to verify the results. ㋡

The folder contains the code needed to experiment and verify the results in the future, thereby I chose to add the majority of files.

Please let me know if I need to perform any necessary changes.
