Support pickleable types in Q object

[archie-ai-code-explain-pr-review]

• The issue arises when using a reference to a non-pickleable type of object, such as dict_keys, in a Q object.
• This causes the | operator to fail, as the Q object cannot be properly serialized and deserialized.
• The example provided demonstrates that Q(x__in={}.keys()) works, but Q() | Q(x__in={}.keys()) raises a TypeError due to the non-pickleable dict_keys object.
• While a workaround is to use Q(x__in={}) instead, it would be desirable for the Q object to support pickleable types, such as lists or tuples, to avoid this issue.
