[modular] Migrate ComponentsManager offload hooks to ModelHook / HookRegistry

follow up TODO on https://github.com/huggingface/diffusers/pull/14304/

the auto-offload hooks used in components mannager are currently accelerate-style hooks: they implement the OOM retry by manually wrapping module entry points, since accelerate's pre_forward/post_forward can't see an exception raised by the forward pass itself.

diffusers now has its own hook system with a new_forward around-hook that covers exactly this case. We should look into migrate the offload hooks to it
