diag: Add support for sending DIAG_CTRL_MSG_DIAG_MODE

Currently, APPS diag does not support sending mode control message
to any processor.  This command notifies the diag software on the
peripheral if it is to run in real-time or non-real-time mode. Add
support for sending the mode control message to the modem and wcnss.
