[PHID] Added SetReport function

This commit just shows other that this option is available and not implemented.
You may use this to determine the Led Lights state of a keyboard or transmit data via RAWHID from the PC.

Quick usage guide:
int length = ((setup.wValueH << 8) | setup.wLength);
USB_RecvControl((uint8_t* data, USB_EP_SIZE); // Needs to be splitted into USB_EP_SIZE packets, not shown here. See HID Project.
