Improve the UI of Press & hold power button settings

The following changes has been made:
- The on/off toggle for Assistant now becomes two radio selectors ("Power Menu" and "Digital Assistant"). This is to make things clearer that Press & hold power button can be configured to power menu.
- The corresponding power menu animation will be shown when "Power Menu" is selected.
- The Assistant specific sensitivity settings and the foot notes are hidden when "Power Menu" is selected.
- Some minor wording updates according to the requests from Assistant / Settings UXW.
