Change NN canonical timings to nanoseconds -- runtime

This CL changes the definition of nn::TimePoint to the same type as
std::chrono::steady_clock::time_point but has changed the underlying
duration representation to use uint64_t. This CL also renames
nn::OptionalTimeoutDuration to nn::OptionalDuration, and changes the
definition to the same type as std::nanoseconds except the underlying
duration representation now uses uint64_t.
