Add benchmarks to GradientSignal. (#6616)

* Add benchmarks to GradientSignal. Cleaned up and rearranged a bit of the unit testing code to make it reusable from a benchmark suite as well. Added set of benchmarks for measuring GetValue(), so that we can compare against GetValues() when it gets added.
