为什么提交这份PR (why to submit this PR)

作为一个rtthread的初学者，对该函数的实现产生了疑惑，尤其是if (stat == RT_THREAD_SUSPEND)部分，当一线程用该函数试图挂起其他线程时（注释中已说明禁止）该函数将返回OK，因为很多情况下一线程运行时其他线程都是被延时挂起让出的。在阅读了函数注释后我猜测项目组原本的意图可能为以下之一：
。该函数本身具有较高权限能挂起其他线程，所以注释警告不应如此做
。该函数在本身只能挂起自身不能挂起其他线程，所以注释说明并报错
。该函数只考虑了挂起自身的情况挂起其他线程可能会未知错误，所以注释警告
但是现在的函数实现不属于以上情况，不应仅返回OK ，且不应存在挂起后挂起（在旧版本为断言），说明函数设置了余量来应对用户行为，以下是对余量的进一步补充

你的解决方案是什么 (what is your solution)

。区分挂起与延迟挂起，挂起应重置计时器，并在覆盖时报告。
。将挂起状态按照rtdef细分NTERRUPTIBLE, KILLABLE, UNINTERRUPTIBLE，并可使挂起状态升级。

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

作者可以看下这个PR，以及相关描述：
修改主要是因为社区有挂起其他线程的需求，但是本身这个行为就是需要可控的，否则一个线程去挂起其他线程会出现问题，这个在rt_thread_suspend的API注释也有体现。所以仅仅是提供了可以去挂起其他线程的一种方法，避免了会出现断言的情况。
因此我不建议再把断言再次加回来的。

Pull Request Overview

This PR aims to enhance the rt_thread_suspend_to_list function in the RT-Thread kernel by improving its behavior when handling already-suspended threads. The changes introduce logic to stop timers when re-suspending threads, allow suspend state upgrades (from INTERRUPTIBLE to KILLABLE/UNINTERRUPTIBLE), and restore an assertion to check that only the current thread can suspend itself when in RUNNING state. Most of the changes are code formatting improvements to align with RT-Thread coding standards.

Key Changes

Enhanced already-suspended thread handling with timer stopping and suspend flag upgrading
Restored self-suspension assertion for RUNNING state threads
Code formatting improvements throughout the file (spacing, alignment)
