Add renderer memory metrics
We will collect per allocator memory usage metrics for the renderer at DidFinishLoad and Shutdown.
GetRendererMemoryMetrics generalizes the memory info collection that was used in RecordPurgeAndSuspendMetrics for use with my new metrics.
GetRendererMemoryMetrics is in RenderThreadImpl because it accesses discardable_shared_memory_manager_.
