[PageLifecycle] Add WPT test for lifecycle's onfreeze callback Since the onfreeze callback is invoked based on an internal decision from the browser, to be able to test the callback, we are adding support for it from chromeGPUBenchmak as well as in chromedriver/WebDriver. This CL focuses on the chromeGPUBenchmark solution. The WPT test itself, verifies that the onfreeze callback is called, and it also verifies that only fetch keepalive is allowed from withing the callback.
