tests: Add tests for _thread module. Includes functionality and stress tests.

import _thread
tests: Format all Python code with black, except tests in basics subdir. This adds the Python files in the tests/ directory to be formatted with ./tools/codeformat.py. The basics/ subdirectory is excluded for now so we aren't changing too much at once. In a few places `# fmt: off`/`# fmt: on` was used where the code had special formatting for readability or where the test was actually testing the specific formatting.

py/modthread: Return thread id from start_new_thread(). In CPython, `_thread.start_new_thread()` returns an ID that is the same ID that is returned by `_thread.get_ident()`. The current MicroPython implementation of `_thread.start_new_thread()` always returns `None`. This modifies the required functions to return a value. The native thread id is returned since this can be used for interop with other functions, for example, `pthread_kill()` on *nix. `_thread.get_ident()` is also modified to return the native thread id so that the values match and avoids the need for a separate `native_id` attribute.
