This experimentally implements taring/untaring the test data for test262 on the v8-side before test isolation and when running the tests. It archives on demand only if the tar is outdated compared to the contained files. This comes with a cost of ~1s extra to run gyp on linux and ~6s extra on windows. Ninja is lightning fast afterwards in detecting changes. Also, we archive only when test_isolation_mode is set and when the test262_run target is required. The archiving itself costs ~30s on all platforms. But as the files will change seldom this shouldn't have a big impact. Extraction on the test runner side is below 2s on mac and linux. The speedup is enormous. Around 5 minutes were spent on download on swarming slaves before, which is now only a few seconds. So total test time for release (no variants), e.g. goes from 8 to 3 minutes.
