Fix #4434: support pickle in serializer

[ultmaster]

Description

The issue that decorator and pickler doesn't play well together is well known. The workaround solution is:

1. On linux: to use a fool class (_pickling_object) which pretends to be the pickled object. We then put the original type, as well as args and kwargs in its __new__ argument.
2. On Win/Mac: to replace the __init__ in-place.

I suspect that their could still be problems when things get complex, e.g., the wrapped class has a custom pickling or __new__. But it can't be worse because the previous pickle doesn't work at all.

This PR also fixes an issue with @nni.trace on super-class.

Fixes #4434.

Checklist

• test case: need to check whether Windows/MAC pipeline works as expected.
• doc

How to test

Test dataloader with traced dataset on Windows, or DataParallel with pl.Classification.
