[Static Runtime] Add schema checks for aten::list (#83753)
Summary:
The previous implementation assumed that there was only one overload and unconditionally tried to convert its input into a string. Some users were running into crashes because of this. Added a new overload for the list overload and schema checks.
Also, I managed to uncover another bug when writing tests for this case (yikes). Returning inputs didn't work because the input cleanup process would destroy the output. Extended `CreateOwnedRefsForSpecialIValues` to fix that.
Test Plan: CI + new unit tests
