AI 143779: am: CL 143727 Make the test runner and results assets of DumpRendertree. This is done so that we could have

1) Lab machines can run layout tests without having build environment setup
  2) We could have different set of pass/fail results per branch
  Also added a simple python script which runs run_layout_tests.py
