Add new fields to GPU benchmarking API.

Add droppedFrameCount, totalPaintTime, and totalRasterizeTime to chrome.gpuBenchmarking.renderingStats().


BUG=chromium:130790, chromium:137756
TEST=Launch Chrome with --enable-gpu-benchmarking and per-tile painting, open a tab to a composited page, and type chrome.gpuBenchmarking.renderingStats(). All the above fields should be present.
