降低系统资源占用率

当执行WFI指令时，会根据比例让出cpu。当命令行等待用户输入时，宿主机cpu占用率为3.3%

TEMU v2.0.0-rc1

TEMU has been refactored since it's first development in Nov, 2023.

Now we deprecated the v1 version, which is written in C++ and only
support the un-privileged risc-v. Our v2 TEMU is now using only C and
I am trying to make it portable, that is this TEMU could even or is focused
to run on a MCU.
