Add getImageData-cpu perf test

To show that willReadFrequently solves crbug.com/1013323, getImageData perf test needs to be run with willReadFrequently set to true. Pinpoint tests will be run against CL 2238991 with getImageData-cpu.html. New perf tests are added to benchmarks_to_shard.json to be included in the benchmark: blink_perf.canvas.
