* [posix] POSIX standard implementation for PSE51

- add some posix's interfaces that we haven't before.
- these PR have passed the interface definition test across gcc platfrom;
- have tested base on qemu-a9 and stm32h750-art-pi.

修改文件头信息

修改ACM32F030 BSP的文件格式

新增BSP驱动中的lib文件

IAR和GCC支持备份

1. 修复不能包含HAL_EFLASH.h问题， 2. 消除GCC编译的几个警告

1. gcc启动文件重命名；2. 文件头信息修改; 3. 硬件timer支持修改

移动 .ignore_format.yml到bsp的目录下

修改目录成相对目录

CCFLAGS is used by gcc and g++ compiler. So CFLAGS should be used for
gcc to avoid passing gcc flags to g++.
