Description
When I try to transplant my code fron Due to Giga r1 Wifi, I found that the opertation `SetCommBreak` will always failed.
Then I check the source code, it seems that it is not supported yet:
(don't have `CDC_SEND_BREAK`)

Research direction
Start with cores/arduino/USB/USBCDC.cpp at the referenced CDC request definitions and compare the corresponding declarations in cores/arduino/USB/USBCore.h from ArduinoCore-sam. Trace how SetCommBreak is handled and verify that CDC_SEND_BREAK is supported without breaking the existing USB CDC behavior.
