feat: 更新CMSIS和GD32C10x_DFP包版本并优化代码

- 升级ARM::CMSIS从4.5.0到6.1.0版本
- 添加ARM::CMSIS-DSP@1.16.2依赖包
- 升级GigaDevice::GD32C10x_DFP从1.0.1到1.5.0版本
- 移除FOC.cpp中未使用的systick.h头文件
- 移除pid.cpp中未使用的<algorithm>头文件
- 更新GD32C10x固件库至V1.7.0版本(2026-01-30)
- 修复ADC驱动中的无符号整数运算问题
- 优化BKP、CAN、CTC等外设驱动中的FlagStatus返回逻辑
- 改进CAN驱动的消息发送和传输停止函数实现
- 修复CRC、DMA、FMC等驱动中的数据类型和变量声明问题
- 清理和修正各驱动文件中的文档注释
