Need a script to run tests in PerformanceTests

Reviewed by Adam Barth.

Add run-perf-tests to run performance tests using parser/resources/runner.js.
Unfortunately, there isn't an easy way of telling which test uses which format
so hard-code directory that uses Chromium perf-bot style (only inspector perf. tests for now).

All test outputs are re-formatted to match Chromium perf-bot style.
