update triton pin to triton 3.5 (#162278)
Summary:
Update PyTorch to the latest Triton release candidate branch (release/3.5.x in triton-lang/triton)
Notably:
* this does *not* include the version number bump from 3.4 -> 3.5 (we'll do that in a follow-up PR)
* sam_fast is still failing, so we've disabled it temporarily https://github.com/pytorch/pytorch/issues/162282 and we are committed to fixing it, ideally before the branch cut but possibly as a cherry-pick into the release branch.
