Inline hooks in ivalue::Future (#57354)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/57354
The ivalue::Future class used to have some hooks, defined as separate protected virtual methods, so that they could be overridden by the CUDAFuture subclass. Now that CUDAFuture has been merged into ivalue::Future those hooks can be "inlined" to where they're used, hopefully making the code more readable as it puts related things closer together.
