Fix issue #22328792: Fix scalability issues in AssistStructure
We can now stream the AssistStructure across processes, avoiding
IPC size limitations for large structures. There is also a new
API that gets called on the VoiceInteractionSession if there is
a failure retrieving the assist data.
Also fix issue #22351981: Runtime restart due to ANR in system server,
getting rid of a deadlock.
And also tweak object lifecycles to try to avoid keeping around
in an app the previous AssistStructure after we request a new one.
