This avoids manipulating `fiber.@current_thread` which ain't very pretty. Crystal::Scheduler is now entirely responsible for setting the current thread. It's also responsible to verify that a making sure a fiber will always be enqueued or resumed on the thread it's been associated to, which is only affecting the `#resume(fiber)` and `#yield(fiber)` methods that are barely used. Lastly, we remove the current_thread store that was always replacing any previous value on context swap. Sadly, this doesn't seem to have any noticeable impact on performance.
