[profiler] Provide line-level info in streaming profiles The line number is associated with each sample along with pointer to the ProfileNode and timeDelta. Once collected line numbers are streamed as an array of integers in "ProfileChunk" trace events. If all the line numbers are zero, the array may be omitted. Otherwise the array length matches length of samples and timeDeltas arrays.
