Summary: Removes delayed scaling from `float8_tensor.py`. After this PR, the invariant is that everything in `float8_tensor.py` requires the scale to be calculated elsewhere. This moves the codebase towards separation of concerns for calculating the scale (via various scaling strategies), separated from creating an instance of `Float8Tensor`. Note that stateful delayed scaling is the reason we need this separation. Test Plan: ``` ./test/test_everything.sh ``` Reviewers: Subscribers: Tasks: Tags: [ghstack-poisoned]
