Move usbd_hid_no_activity() hook from usbd_user_hid.c to
DAP_queue.c and rename it to DAP_activity_blink().
In this new location it can be used to skip HID LED blinking in
traffic from USB bulk as well.
Add default behaviour of skipping HID blink of DAP serial & MSD
activity to the default hook for all projects.
Remove customised hooks in the artemis & micro:bit projects as they
are no longer needed.
