BootLoader重构: 适配HC32F460KETA并按传感器通用串口升级协议V1.1改造

主要修改事项:
1. 器件更换: HC32F460PETB改为HC32F460KETA, 更新MDK工程(uvprojx/uvoptx/RTE), 调试器切换为Segger J-Link
2. 新增自定义分散加载文件MDK/BootLoader_custom.sct
3. 新增传感器通用串口升级协议V1.1.xlsx(协议文档)
4. 时钟系统: 取消外部晶振, 改用内部HRC 16MHz -> MPLL 200MHz
5. 删除未使用模块: FatFS/SDCard/SHT20/SX127x(Lora)/AD7924/spiflash/ADS1231/Encryption及LoraTask/CatOneTask/RS485Task/DebugCmd/AppTask, 清理工程IncludePath
6. bsp: BootPara_t参数结构体与GateWay APP对齐(新增GwMac/SvrAddr/SvrPort/LoraFreq/通道配置), 新增RS485 Ch1(USART2)升级通道及RS485 Ch2(USART3)配置, GPIO仅保留RS485方向控制(PC7/PB13)
7. main: 设备MAC固定地址由0x2800改为0x4000并按宏构造(VerInfo/PrjNum/GwNum), 帧头由0x7a改为0x7D并带DevMac字段, 增加MAC匹配(支持0xFF广播), 升级命令更新(0x01 ACK/0x02请求数据/0x81请求/0x82下发), CRC32校验后写参数并复位
8. 跳转APP前关闭全局中断/停SysTick/禁用NVIC中断, 避免残留中断干扰APP
9. Flash擦除仅擦APP区(不擦参数区), 首次运行检测及旧参数区默认值补齐
10. 修复驱动头文件乱码注释(hc32f460_dcu.h/hc32f460_icg.h)
