为什么提交这份PR (why to submit this PR)

修复 #11124

STM32 部分 GCC 链接脚本使用 .data : AT(_sidata) 指定初始化数据的加载地址，但未将其关联到对应的 ROM/CODE 内存区域。因此，代码和常量未超限、加上 .data 初始化镜像后超限时，链接仍可能成功，生成超出配置容量的固件。

你的解决方案是什么 (what is your solution)

参考ST官方的链接脚本：跳转地址
修改方式相同：

  /* Used by the startup to initialize data */
  _sidata = LOADADDR(.data);

  /* Initialized data sections into "RAM" Ram type memory */
  .data :
  {
    . = ALIGN(4);
    _sdata = .;        /* create a global symbol at data start */
    *(.data)           /* .data sections */
    *(.data*)          /* .data* sections */
    *(.RamFunc)        /* .RamFunc sections */
    *(.RamFunc*)       /* .RamFunc* sections */

    . = ALIGN(4);
    _edata = .;        /* define a global symbol at data end */

  } >RAM AT> ROM

注：脚本数量太多，但是修改比较简单，就使用AI自动化修改了下。

该修复会暴露一个新的问题：使用 .data >RAM AT>ROM 后，后续 .stack 的加载地址变到了 RAM，在llvm工具链下生成的bin文件大小异常：

解决方案： 官方的链接脚本stack放在了.bss后，因此没问题，该问题的正确解决方式是 .stack 添加 noload

.stack (NOLOAD) :
{
    /* 原有内容 */
} >RAM1
