[flake8-logging] Implement LOG002: invalid-get-logger-argument (#7399)

## Summary

This PR implements a new rule for `flake8-logging` plugin that checks
for
`logging.getLogger` calls with either `__file__` or `__cached__` as the
first
argument and generates a suggested fix to use `__name__` instead.

Refer: #7248

## Test Plan

Add test cases and `cargo test`

+/// ## What it does
+/// Checks for any usage of `__cached__` and `__file__` as an argument to
+/// `logging.getLogger()`.
+///
+/// ## Why is this bad?
+/// The [logging documentation] recommends this pattern:
+///
+/// ```python
+/// logging.getLogger(__name__)
+/// ```
+///
+/// Here, `__name__` is the fully qualified module name, such as `foo.bar`,
+/// which is the intended format for logger names.
+///
+/// This rule detects probably-mistaken usage of similar module-level dunder constants:
+///
+/// * `__cached__` - the pathname of the module's compiled version, such as `foo/__pycache__/bar.cpython-311.pyc`.
+/// * `__file__` - the pathname of the module, such as `foo/bar.py`.
+///
+/// ## Example
+/// ```python
+/// import logging
+///
+/// logger = logging.getLogger(__file__)
+/// ```
+///
+/// Use instead:
+/// ```python
+/// import logging
+///
+/// logger = logging.getLogger(__name__)
+/// ```
+///
