[M251/M252] PWM Capture Rotary

This sample code uses the M251/M252 series to capture the A and B phase square wave signals generated by a rotary encoder switch. By determining the relative position of phases A and B, it identifies the rotation direction and records the rotation position, then outputs the captured results via UART.
