xushenghao 21e9d75e40 Implement DMA for USART1 reception and update FreeRTOS configuration 
- Modified shell_port.c to replace interrupt-based UART reception with DMA.
- Introduced a DMA buffer for UART data and adjusted the shell buffer handling.
- Added idle interrupt handling to process incoming data from the DMA buffer.
- Updated freertos_f407.ioc to configure DMA for USART1 RX and TX.
- Enabled necessary NVIC interrupts for DMA streams associated with USART1.
