Update USB dialog for USB-C power option

Also includes a bit of visual updates, options now have summaries
as well.

Code has been refactored a bit, and is more flexible to easily
support any kind of power/data flow combination once its time
to support that.

Currently devices don't have USB-C ports, they can be simulated
with the following commands:
  $ adb shell dumpsys usb add-port "matrix" dual
  # ?s control whether these can be changed
  $ adb shell dumpsys usb connect-port "matrix" ufp? sink? device?
  # Do testing here
  $ adb shell dumpsys usb disconnect-port "matrix"
  $ adb shell dumpsys usb remove-port "matrix"
  $ adb shell dumpsys usb reset
  # Use the help for more info
  $ adb shell dumpsys usb -h
