applications: nrf_desktop: Imply partial flash erase for USB next

Change implies nRF SoC flash partial erase for USB next stack. This is
done to improve stability of the USB next stack. The partial erase
feature works around device errors that might be reported by Windows USB
host in Device Manager if USB cable is connected while erasing secondary
image slot in the background.
