  Add new test runner harness.
  
  The ANGLE test harness is a harness around GoogleTest that provides
  functionality similar to the Chromium test harness. It supports:
  
   * splitting a test set into shards
   * catching and reporting crashes and timeouts
   * outputting to the Chromium JSON test results format
   * multi-process execution
  
  Unit tests are added in test_utils_unittest.cpp.
