Bluetooth: Add sample implementing HIDS

This adds a sample that implements HID Service peripheral, the current
descriptor map is for a generic mouse so when connecting to a Linux box
it will create a input device like in the following output:

input: Test HoG mouse as /devices/virtual/misc/uhid/0005:1D6B:0246.0035/input/input98
hid-generic 0005:1D6B:0246.0035: input,hidraw2: BLUETOOTH HID v5.29 Mouse [Test HoG mouse] on XX:XX:XX:XX:XX:XX
