#### 为什么提交这份PR (why to submit this PR) - 修复ch32v307v-r1 board.h 中变量_stack_size未声明BUG - 提供ch32v307v-r1动态堆内存分配（宏开关）代码 - ch32v307v-r1 MD文档新增烧录方式，作为烧录后无运行结果的替代方案 #### 你的解决方案是什么 (what is your solution) - 去掉_stack_size未声明变量 - 动态分配内存堆，将堆起始地址放在.bss段结尾，堆结束地址放在.stack段开头[详情](https://club.rt-thread.org/ask/article/001065082e9ae611.html) - 将烧录工具替换为WCH-LinkUtility #### 在什么测试环境下测试通过 (what is the test environment) - 开发工具: RT-Thread Studio - 测试板卡：ch32v307v-r1评估板 - 烧录工具：WCH-LinkUtility
