[internal] Refactor MyPy config file setup #12593

mypy/rules.py is really complex and I'm having a hard time understanding it while adding a tool lockfile. This is the first of a couple refactors.

Here, we better encapsulate the config file code by moving into mypy/subsystem.py with a dedicated rule. This allows us to make the unit test more comprehensive.
