Far c1c2be2a87 refactor: 文件系统Open性能优化 
优化包括：
1. 提供VnodeLookupFullpath接口，如果路径是规范化的路径，则调用此接口可减少一次vfs_normalizepath接口的调用;
2. fatfs open钩子函数FIL和buffer同时malloc，减少一次malloc调用，同时去除不必要的数据写回;
3. 其他小细节的优化。

Leon Chan e4a06623ce fix: change the execFile field in TCB to execVnode 
TEE需要借用TCB中的execFile来校验打开的文件，pagecache修改后，可执行程序在mmap之后，会被立即关闭，因此将execFile改为execVnode

Guangyao Ma 27dca4d857 feat(vfs): vfs支持FD_CLOEXEC标记 
首先，POSIX规范规定文件描述符需要支持close-on-exec属性，修改前的vfs不支持close-on-exec，当exec系列函数执行时，进程所有的文件将会被关闭（0，1，2也重新被打开）。但是，系统有些时候是不能在exec时关闭全部文件的，例如在执行exec之前，就需要重定向进程的某些文件描述符时（使用dup2），就希望该文件不被关闭，继续保持重定向属性，shell执行进程并重定向其标准输出到文件，这是我们经常做的事情。

BREAKING CHANGE:
执行exec类函数后，进程拥有的文件描述符情况发生变化：修改前，默认关闭所有的进程文件描述符，0，1，2重新打开；修改后，除非文件描述符拥有FD_CLOEXEC标记，否则该描述符不会被关闭。
