How buffer overflow in SCSI command handling happens in C and how to fix it

A critical buffer overflow vulnerability was discovered in libretro-common's CDROM handling code where the `cdrom_send_command_win32()` function copied an arbitrary number of bytes into a fixed 16-byte SCSI Command Descriptor Block (CDB) buffer without validation. This vulnerability could allow an attacker using a malicious CDROM image or USB device to corrupt memory and potentially execute arbitrary code. The fix adds a simple bounds check before the memcpy operation to ensure cmd_len never exc
