8e9bbd31 - Make DataPtr extraction in CUDAFuture faster for Python values (#56918)

Make DataPtr extraction in CUDAFuture faster for Python values (#56918) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/56918 Re-importing a Python module each time is a bit expensive, and it's unnecessary because this is a private module which won't change and thus we can cache the value once we first extract it. ghstack-source-id: 128184666 Test Plan: CI Reviewed By: mrshenli Differential Revision: D27985910 fbshipit-source-id: be40ae9b67ab8ea6c07bc2cb9a78d2c2c30b35d3
