Cache AndroidBlockGuardPolicy to avoid allocation.
Every incoming Binder call ends up triggering a BlockGuardPolicy
update, which would thrash between new AndroidBlockGuardPolicy
instances and BlockGuard.LAX_POLICY, causing GC churn.
This change avoids the extra allocations by recycling a single
AndroidBlockGuardPolicy in a ThreadLocal. Worst-case thrashing case
is now 10% faster; from 7.46us to 6.65us.
