拉取/合并请求描述：(PR description)

为什么提交这份PR (why to submit this PR)

lwp_syscall.c contains more than eleven thousand lines covering memory, file system, socket, process, IPC and time syscalls. The single file is difficult to navigate and review.

你的解决方案是什么 (what is your solution)

  • move syscall implementations into components/lwp/syscall/
  • group syscalls by subsystem (memory, file, socket, process, IPC, time)
  • add a shared syscall dispatch table and internal header
  • register the new directory from the LWP build script
  • keep all 165 syscall entry points and behavior unchanged

请提供验证的bsp和config (provide the config and bsp)

  • BSP: bsp/qemu-virt64-riscv (RT-Thread Smart)
  • .config: CONFIG_RT_USING_SMART=y
  • action: local build not run; the RISC-V musleabi toolchain is not available in this environment, CI will verify the build

This PR is a mechanical refactor. There is no functional change.

  • 所有变更均有原因及合理的，并且不会影响到其他软件组件代码或BSP All modifications are justified and not affect other components or BSP
  • 对难懂代码均提供对应的注释 I've commented appropriately where code is tricky
  • 代码是高质量的 Code in this PR is of high quality
  • 已经使用clang-format 源码格式化工具确保格式符合RT-Thread代码规范 This PR has been formatted with clang-format and complies with RT-Thread code specification
  • 如果是新增bsp, 已经添加ci检查到.github/ALL_BSP_COMPILE.json 详细请参考链接BSP自查

👋 感谢您对 RT-Thread 的贡献！Thank you for your contribution to RT-Thread!

为确保代码符合 RT-Thread 的编码规范，请在你的仓库中执行以下步骤运行代码格式化工作流（如果格式化CI运行失败）。
To ensure your code complies with RT-Thread's coding style, please run the code formatting workflow by following the steps below (If the formatting of CI fails to run).

🛠 操作步骤 | Steps

  1. 前往 Actions 页面 | Go to the Actions page
    点击进入工作流 → | Click to open workflow →

  2. 点击 Run workflow | Click Run workflow

  • Use workflow from 保持默认分支（通常为 master）
    Keep the default branch (usually master) in Use workflow from
  • 在 branch 输入框填写 PR 分支 pr/lwp-syscall-split
    Enter PR branch pr/lwp-syscall-split in the branch field
  • 设置需排除的文件/目录（目录请以"/"结尾）
    Set files/directories to exclude (directories should end with "/")
  1. 等待工作流完成 | Wait for the workflow to complete
    格式化后的代码将作为独立提交推送至你的分支。
    The formatting changes will be pushed to your branch as a separate commit.

完成后，提交将自动更新至 pr/lwp-syscall-split 分支，关联的 Pull Request 也会同步更新。
Once completed, commits will be pushed to the pr/lwp-syscall-split branch automatically, and the related Pull Request will be updated.

如有问题欢迎联系我们，再次感谢您的贡献！💐
If you have any questions, feel free to reach out. Thanks again for your contribution!
