[RootCanal] Add support for LinkPolicy and RoleChange in RootCanal 

Needed for HID PTS tests. We just fake the link policy and our current
role by tracking them locally, rather than using LMP to coordinate with
the peer. This can be changed at a future date if a test depends on this
working.

Test: HID PTS tests
