feat: Creating one py_binary per main module (#1584)

Many existing Python repos don't use `__main__.py` to indicate the the
main module. Instead, they put something like below in any Python files:

```python
if __name__ == "__main__":
  main()
```

This PR makes the Gazelle extension able to recognize main modules like
this, when `__main__.py` doesn't exist. This reduces the need to create
`__main__.py` when enabling Gazelle extensions in existing Python repos.

The current behavior of creating single `py_binary` for `__main__.py` is
preserved and takes precedence. So this is a backward-compatible change.

Closes #1566.
