zero323 665817bd4f [SPARK-33457][PYTHON] Adjust mypy configuration
### What changes were proposed in this pull request?

This pull request:

- Adds following flags to the main mypy configuration:
  - [`strict_optional`](https://mypy.readthedocs.io/en/stable/config_file.html#confval-strict_optional)
  - [`no_implicit_optional`](https://mypy.readthedocs.io/en/stable/config_file.html#confval-no_implicit_optional)
  - [`disallow_untyped_defs`](https://mypy.readthedocs.io/en/stable/config_file.html#confval-disallow_untyped_calls)

These flags are enabled only for public API and disabled for tests and internal modules.

Additionally, these PR fixes missing annotations.

### Why are the changes needed?

Primary reason to propose this changes is to use standard configuration as used by typeshed project. This will allow us to be more strict, especially when interacting with JVM code. See for example https://github.com/apache/spark/pull/29122#pullrequestreview-513112882

Additionally, it will allow us to detect cases where annotations have unintentionally omitted.

### Does this PR introduce _any_ user-facing change?

Annotations only.

### How was this patch tested?

`dev/lint-python`.

Closes #30382 from zero323/SPARK-33457.
