Stop warning that macOS support is experimental

Previously this warning would be printed each time a `Tracker` was
constructed, which caused a lot of noise when `pytest-memray` was being
used, since it creates one `Tracker` per pytest test. Since we haven't
heard any reports from users of any cases where things are actually
broken on macOS, and since our documentation lists all of the known
limitations in considerable detail, we've decided to stop considering
macOS support to be experimental, and to drop the warning.
