DDPO Example

[abhijitpal1247]

**Is your feature request related to a problem? No.
A clear and concise description of what the problem is.
Current implementation of DDPO supports only TPU.
A general implementation that also supports GPU would be a great addition to the existing examples of diffusers library.

Hi, I'd be interested in working on this if the DDPO authors don't pick this up :).

I have opened a PR with some rough initial code at #3860.
