[issue41052] Opt out serialization/deserialization for heap type

[Dong-hee Na]

See https://bugs.python.org/issue40077#msg371813

We noticed that heap type has different behavior about serialization/deserialization.

Basically it can occur the regression issues.

Two things needed.
1. opt out serialization/deserialization for converted modules.
2. Add unit tests to check whether their serialization is blocked.
3. If the module is already ported to 3.9 backport patch is needed.
Long term
- Add the object.reduce() and/or update pickle can be smarter
