  Automate testing of capture_replay
  
  automation script will:
  1. compile all tests in angle_end2end with framecapture enabled
  2. run each test with frame capture
  3. compile CaptureReplayTest with cpp trace files
  4. Run CaptureReplayTest
  
  Test: run_tests_with_framecapture.py
  Bug: angleproject:4749
