Base files added for HID detection screen.
Added files for Bluetooth Human Input Devices detection on OOBE flow.
*oobe_screen_hid_detection.* files provide screen view, no details, only base.
*hid_detection_screen_handler -- corresponding webui handler
*hid_detection_screen and hid_detection_screen_actor provide oobe screen interaction API
*all other files changed to wire up the new screen.
As long as no invocation calls added, current OOBE flow isn't changed visually.
