usb: thor: add screen support

cmd_thordown.c:
- add libtizen header
- change error handling for thor init
- add call to draw_thor_fail_screen() on error

f_thor.c:
- thor_init(): return -EINTR on ctrl+c or if power key was pressed 3 times
- thor_rx_data(): return -EINTR when pressed ctrl+c on data receiving
- add display simple info screen before cable is not connected
- add display download screen when connection is established
- update download progress bar if data receiving
