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>
