arvinzzz 753d86014b feature: 支持newlib与musl切换
系统支持newlib,并且可以与musl-C自由切换

1. 新增newlib支持,适配newlib的预留钩子,针对系统能力适配newlib头文件(补充宏定义,结构体定义,posix能力开关),
  采用标准C与自研posix接口声明与结构体定义混合作为C库
2. 梳理kal的依赖关系,kal作为内核对外提供的标准接口,下属包含cmsis、libc、posix。
  cmsis为内核对cmsis接口的支持,libc为内核对三方C库的适配及使用,posix为内核自研提供的posix标准接口。
  若采用musl-C,则kal中选取libc/musl,posix共同作为C库对外支持;
  若采用newlib-C,则kal中选取libc/newlib,部分posix共同作为C库对外支持。
3. fs整理,components/fs下提供基于posix标准的接口改为内部对外接口,供musl以及newlib切换 适配使用
