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.

tests/thread: Adjust thread tests so most are able to run on rp2 port. The aim of this commit is to make it so that the existing thread tests can be used to test the _thread module on the rp2 port. The rp2 port only allows up to one thread to be created at a time, and does not have the GIL enabled. The following changes have been made: - run-tests.py skips mutation tests on rp2, because there's no GIL. - run-tests.py skips other tests on rp2 that require more than one thread. - The tests stop trying to start a new thread after there is an OSError, which indicates that the system cannot create more threads. - Some of these tests also now run the test function on the main thread, not just the spawned threads. - In some tests the output printing is adjusted so it's the same regardless of how many threads were spawned. - Some time.sleep(1) are replaced with time.sleep(0) to make the tests run a little faster (finish sooner when the work is done). For the most part the tests are unchanged for existing platforms like esp32 and unix. Signed-off-by: Damien George <damien@micropython.org>

# Initialise variables (also preallocate their spot in the globals dict so the
# globals dict is not resized while threads are running).
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. Fixes issue #12153. Signed-off-by: David Lechner <david@pybricks.com>
