[TensorExpr] Break circular dependency of shared pointers in MemDependencyChecker. (#65600) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/65600 Previously AccessInfo owned two maps: dependencies_ and dependents_, which represented an edge in dependency graph. These two maps were holding shared pointers and thus each edge immediately became a cycle, which resulted in memory leaks. This PR makes one of the ends of these edges weak pointer thus breaking the loop.
