Log Accessibility serialization and unserialization time taken.

We are already logging the worst serialization times as UKM metrics,
this change logs all times so we can track real world performance over
time. This will be useful for measuring the real world perf impact
of changes that alter what or how we serialize accessibility
nodes.
