feat(device): 添加早期诊断功能并优化SPI通信实现

Browse Source 
- 在startup_gd32e50x_cl.s中添加USART0早期诊断代码，在Reset_Handler中
  发送'R'字符以确认启动过程

- 修改system_gd32e50x.c中的时钟初始化逻辑，支持动态检测当前时钟源
  （PLL或IRC8M）并相应调整串口波特率设置

- 在系统时钟配置函数中添加HXTAL故障诊断输出，当外部晶振启动失败时
  通过USART0输出"HXTAL FAIL"错误信息

- 在AppSpiCommand类中实现DMA传输机制，使用DMA0_CH2进行SPI0数据发送，
  提升传输效率并与BOOT端保持一致

- 重构SPI命令处理逻辑，优化PING命令响应格式，包含APP和BOOT版本信息
  以及运行时间统计

- 添加事务过滤机制，忽略全0xFF或全0x00的数据包以及短帧

- 更新配置文件定义APP固件版本号和OTA配置页面地址

- 修复region配置文件中的ROM大小数值精度问题

- 调整NVIC中断优先级设置，优化SPI中断处理
