  Add DrawElementsPerf test
  
  This is a follow-up CL for
  https://chromium-review.googlesource.com/c/544634/.
  In this commit, we add drawElements perf test for d3d9, d3d11 and
  OpenGL. Specially, we test DrawElements with unchanged index buffer
  every frame and changed index buffer every frame. This is also a
  preparation for further remove IndexRange in validation.
  Paste a set of data (repeated 30) for reference on Intel skylake
  Win10 desktop.
  DrawElementsPerfBenchmark.Run/d3d11:
  mean: 13186.1666667, stddev: 200.479605502,
  truncated mean: 13192.5416667, stddev: 156.284190704
  DrawElementsPerfBenchmark.Run/d3d11_index_buffer_changed:
  mean: 43.6, stddev: 4.02160830183,
  truncated mean: 43.5833333333, stddev: 2.97092391166
