refactor: 优化csky/xtensa/riscv架构中断管理框架 

方案描述：
1、在最外层arch/include/los_interrupt.h中定义数据结构、声明对外接口；
2、在arch/xxx/common实现xxx架构中断通用的接口定义与声明；
3、在arch/xxx/yyy中实现针对xxx架构的差异化实现;
4、修改宏数值，适配整个中断管理框架

BREAKING CHANGE:
优化csky/xtensa/riscv架构中断管理框架对外变更描述：
1、宏OS_ERRNO_HWI_OPS_FUNC_NULL数值改为0x0200090c

Close: #I7DRTP
