Binder cache for Bluetooth getBondState()

Bug: 140788621

This includes a change to AdapterService that invalidates the caches after
cleanup has been recorded, and after the bluetooth service starts.  The bug
occurred when switching users.

Test: A special build that puts the PropertyInvalidatedCache in verification
mode was loaded on the device.  Then one iteration of MPTS was executed.  No
cache inconsistencies were found and no SELinux violations (associated with
the binder cache) were found.  The number of cache misses was approximately
10% of the total binder calls.  Then the phone was cycled through bluetooth
pairing and unpairing events.
