首创ubuntu下cw32l031的vscode+gcc工程创建、下载、调试 2023-07-14

目前官方提供CW32L083只提供了MDK、IAR下的固件库、启动文件。我有过成功CW32L083的项目移植的经验，现在成功的把CW32L031的工程移植到ubuntu下面，实现了VSCODE的GCC工程模版。现在将移植的过程与结果分享如下：
1. CW32L031与CW32L083同属arm-cortex-M0+系列，通对比MDK下的启动汇编程序，发现除flsh与内存大小不同之外，中断、外设基本差不多。因此，我只需要修改。cw32L031、startup_cw32l031_gcc.s、CW32L031_FLASH.ld这三个文件就可以了。
2. 同时将相关的外设驱动库更换成cw32l031更换过来就实现了工程的移植。
3. 在ubuntu下面还需要安装wch-link的驱动。
3、移植好后，修改makefile的固件名称、路径就可以实现工程的编译、下载、以及GDB调试。
结果：
1. 编译：
