refactor(kthread): Refactoring kernel threads to remove inlining.

Previous versions of the os memory inline within the kthread, making the adaptation of different os more complicated (because each thread deletion mechanism is different, the inline memory needs to wait until the thread is recycled before release); Kernel threads are now simplified, and the memory of thread objects remains in mr-X, while the memory of threads is managed by the os.
