$beep_status can't work properly

[KnightSin]

hi!

I found a bug and tried to fix it

The problem is located at Firmware\Grbl_Esp32\src\mks\MKS_TS35.h

Change the contents of this file to the code in next

line 29

#if defined(USE_BEEP)
#define BEEP_ON ts35_beep_on()
#define BEEP_OFF ts35_beep_off()
#else
#define BEEP_ON
#define BEEP_OFF
#endif
