[HUST CSE][document] Fix some comments, invalid grouping commands and warnings in Doxygen.

将Doxygen输入文件（由Doxyfile中的INPUT定义）中的失效Doxygen分组指令（如/*@*/和/*@}*/）更改为有效的分组指令（如/**@*/和/**@}*/）；（此处只对INPUT中的文件做了修改，bsp目录下和libcpu目录下存在近万个失效的Doxygen分组指令，但由于不作为文档的输入文件且这些文件过于庞大老旧，没有对这些文件中的无效指令做修改）
将图片文件统一放入了images目录下；
修改了Doxyfile和部分Doxygen注释，使得Doxyfile能够定位到新的代码路径且不受重复实现的影响；
解决了一些注释中的参数名不匹配、参数多余/缺失等问题。
