  Perf tests: Add screenshot capture mode.
  
  This adds a "--screenshot-dir" argument to capture screenshots.
  If we're running with screenshot capture then the test will
  early exit after the first capture. The screenshots use the same
  naming pattern as the test name:
  
  TracePerfTest.Run/vulkan_trex_200 -> angle_vulkan_trex_200.png
  
  Note the screenshot dir is relative to the test binary directory,
  not the CWD. Also adds a PNG saving utility function.
