Bluetooth Auto-connect per user, fix multidevice connections

When auto connecting to devices on bluetooth, store and try devices per
user. Added a CarUserService that is created for the current user on
UserSwitch.  The CarUserService deals with scenarios where the
CarService, running as a System User, doesn't get to listen to events
from processes running as the current user.
Fix the issue where when 2 phones were connected on HFP, auto-connect
only connects to one.
Other cleanup and slight code re-org

Bug: b/35324581
Bug: b/37305537
Test: Manually tested by switching between different users and connecting
to multiple phones.
