fix(kernel): properly release mutexes in _thread_detach_from_mutex()

[

为什么提交这份PR (why to submit this PR)

在RT-Thread中，rt_thread_detach通过调用链_thread_detach_from_mutex->rt_mutex_release无法释放被分离线程持有的互斥锁，原因在于：rt_thread_detach要求调用线程与被分离线程不同，而rt_mutex_release则要求调用线程必须为锁的持有者，这两个相互矛盾的条件导致锁无法被正常释放。

你的解决方案是什么 (what is your solution)

可以通过重构互斥锁释放逻辑来解决这个问题：首先提取原始rt_mutex_release的核心实现为_rt_mutex_release函数，然后基于此实现新的rt_mutex_release，确保其行为与旧版本完全一致。这样既保持了原有接口的兼容性，又为后续扩展奠定了基础。

基于_rt_mutex_release，可以实现新的rt_mutex_force_release函数，该函数将绕过持有者检查逻辑。在_thread_detach_from_mutex流程中，用这个新函数替换原来的rt_mutex_release调用，这样即使当前线程不是互斥锁的持有者，也能正确释放被分离线程持有的锁资源。
