[torch.compile] fix graph break problems partially (#5453)

* fix: controlnet graph?

* fix: sample

* fix:

* remove print

* styling

* fix-copies

* prevent more graph breaks?

* prevent more graph breaks?

* see?

* revert.

* compilation.

* rpopagate changes to controlnet sdxl pipeline too.

* add: clean version checking.
