Revert "Reference implementations for rot90, roll, atleast_1d,2d,3d (#78080)"
This reverts commit 96c134854d4dbc418cdc0ec82959476ddac8068e.
Reverted https://github.com/pytorch/pytorch/pull/78080 on behalf of https://github.com/malfet due to as it broke XLA on trunk (see https://github.com/pytorch/pytorch/runs/6678429656?check_suite_focus=true ) and the same pattern were observable on PR CI https://github.com/pytorch/pytorch/runs/6672733779?check_suite_focus=true
