Tugsbayasgalan Manlaibaatar b756b580fb Improve fake tensor leakage detection in export by not relying on gc too much (#163516) ...

Previously we relied on gc to get the snapshot of fake tensors before and after export to get list of fake tensors that are created during export. This caused some flakiness in our test suite (https://github.com/pytorch/pytorch/issues/162232). it seems super hard to make gc deterministic, so we just instrument fake tensor creation which seems lot better. In addition, it is also quite faster than previous approach becuase we are no longer manually triggering garbage collector.
