Support tracing metrics for measureValueAsync method

Support tracing metrics for measureValueAsync method

This exposes PerfTestRunner.addRunTestStartMarker & 
PerfTestRunner.addRunTestEndMarker so that async perf tests can add their own 
markers to get trace metrics. An example of how this works is shown in
third_party/WebKit/PerformanceTests/TestData/simple-blob-measure-async.html.

Daniel: I found about this when BlobRequest metrics are seem to be double count.
This is probably already a bug in the current blob_storage benchmark.
