refactor(wait_queue): 重构等待队列机制，引入Waiter/Waker模式 (#1452)

* refactor(wait_queue): 重构等待队列机制，引入Waiter/Waker模式

- 重构WaitQueue，引入Waiter/Waker模式避免唤醒丢失
- 统一等待接口，提供wait_event_interruptible/uninterruptible方法
- 重构futex、epoll、eventfd、semaphore、completion等模块使用新等待队列
- 优化进程等待子进程退出逻辑，使用新等待队列接口
- 添加等待队列设计文档说明新机制

* feat: 添加SKIP_GRUB选项以支持在CI或无图形界面环境中跳过GRUB安装

* fix: 修复信号处理和futex唤醒的错误码

- 在sys_rt_sigtimedwait中消费信号后及时刷新HAS_PENDING_SIGNAL状态，避免后续等待路
径误判
- 将futex可中断唤醒的错误码从ERESTARTSYS改为EINTR，以符合Linux语义

* ci: Update Docker image source in test-x86 workflow

- Changed the Docker image source from `docker.cnb.cool/dragonos-community/dragonos/dragonos-dev:v1.19` to `dragonos/dragonos-dev:v1.19` for consistency in CI workflows.
