Adds RuntimeStats counters for HeapBrokerInitialization, Serialize, SerializeMetadata and Finalization phases. These happen only on main thread. In a followup cl we will also add counters for other phases that could happen on main thread or background thread. Earlier RecompileSynchronous was used to measure the time spent in Concurrent, non Concurrent and Concurrent finalize phases. This cl replaces them with OptimizeConcurrent, OptimizeNonConcurrent and OptimizeConcurrentFinalize counters. This cl also renames RecompileConcurrent to OptimizeBackground to make it clear this measures the background component of optimization. This also updates names of trace events to be in-sync with RuntimeStat counters.
