If device doesn't support MIDI, don't show MIDI in "Use USB for" menu
when USB cable is connected.
(Selecting MIDI will crash the Settings app.)

Turns out there are valid data modes in host mode (like midi).
Need to allow these through for the dialog to set the proper
current state.

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
