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.

Tugsbayasgalan Manlaibaatar	0e9f9c3a61	Fix inconsistent test and add new tracer as config (#162558) ... It is better to have the new tracer as global config that can be manipulated easily. Also I believe dynamo-like config infra is useful instead of relying on custom way of patching stuff.
