Looks super clean!
I just ran some benchmarks to confirm if the changes don't have any detrimental effect on the speed-memory trade-off (code) and they look alright to me.
Would maybe also run all the group offloading tests on the GPU, too.

@sayakpaul Could you take another look? added a test as well |

The current implementation, after many of the recent updates, is hard to understand or debug/reason through. There is also one code path that seems completely unused (see the removed
self.offload_to_disk_pathrelated changes and the call intoself._onload_from_disk).This PR tries to refactor and clean up some of the implementation so that implementing new changes is easier in the future.
