MNT Copy the CPython resource tracker code rather than derive from it

[lesteve]

This may be preferable to avoid being affected by a CPython change in the future as in #459, especially since now we override the _ensure_running_and_write method.

I tried to mostly add the CPython 3.13.7 resource_tracker code from the non-overriden methods and left things out where I was able to quickly see it was not used e.g. self._reentrant_messages.

We could align the code even more in a further PR, e.g. single vs double quotes (easy mostly needs to tell black to ignore this file) or some other things (reentrant logic, some small logic change in main, etc ...).

There are teardown errors after tests/test_reusable_executor.py::TestExecutorDeadLock::test_crash_races[13] and subsequent tests on CPython 3.14.0rc2t.

Maybe we should directly sync with the code of the current main of CPython instead of CPython 3.13.7.

+1 for using the same code style as in CPython and configure the linter to ignore this file to ease future synchronizations.
