b/12068020 Add a way to add uniqueness to device descriptors. Do not merge
Cherry pick from https://googleplex-android-review.git.corp.google.com/#/c/398226/
This adds an integer to the descriptor of devices without uniqely
identifying information. It will reuse values that are no longer
in use, so if you remove a single device and attach a different
identical device it will appear to be the same device.
TODO: Derive uniqueness from USB port when possible. This version
will generate different descriptors for each half of a USB keyboard
that shows up twice.
