[torch export] replace traceback.extract_stack with CapturedTraceback.extract (#121449)
Summary:
with a simple bench in TestDeserializer.test_basic function:
```
time_start = time.time()
for i in range(1000):
self.check_graph(MyModule(), inputs)
warnings.warn(f"time_taken: {time.time() - time_start}")
```
and forcing FakeTensorConfig.debug to True, record_stack_traces to True, logging level to debug, it shows that the the changed code is consistently ard 20 secs faster (~90s vs originally ~110s)
Test Plan:
test passed, see summary
compared debug trace before and after:
- exactly the same for fake tensor and proxy callsite https://www.internalfb.com/intern/diffing/?paste_number=1189883685
- slightly different for the user frame in proxy node https://www.internalfb.com/intern/diffing/?paste_number=1189884347
