Add function ispackage to stdlib inspect

[Xiaokang2022]

Feature or enhancement

Proposal:

Currently, the built-in module inspect lacks a function to determine whether an object is a package or not. This is a small but useful feature.

According to the documentation, this feature should not be difficult to implement, and we should add it to the standard library:

1. Definition of a package
2. module.__package__
3. module.__name__
4. module.__spec__

I've tried to implement this feature and will make a PR later.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

My idea for implementing this feature is:

flowchart LR
    1(obj)
    2{is module?}
    3{hasattr 
    __ path __?}
    4(pkg)

    1 --> 2 --Y--> 3 --Y--> 4
