Add Microchip SAM series MCU support for RT-Thread (#5771)

* Add Microchip SAM series MCU support for RT-Thread Add Microchip SAM series MCU support for RT-Thread, including SAM Cortex-M0+, M4F and M7. * Add bsp directory to ignored check list Add bsp directory to ignored check list, add microchip /samc21/same54/same70 to workflows list * remove STDIO definition and bug fix 1. remove STDIO code from Microchip official BSP. 2. bug fix of SAME70 hpl/hpl_usart.c, samc21&same54 hpl/hpl_sercom.c baudrate update interface. 3. Add RT-Thread standard STDIO implementation on Microchip SAM MCU. * add CAN driver & example and script fix Add CAN driver and example for SAMC21/SAME5x/SAME70 and fix rtconfig.py issue(unused space might result link error) * Add Chinese version README Add Chinese version README for SAMC21/E54/E70
