Code Review
This pull request updates the web benchmark recorder to support asynchronous rendering and modifies CI presubmit settings for several Linux benchmarks. Feedback recommends removing commented-out code in the CI configuration to improve readability and using the local view object instead of the global PlatformDispatcher for rendering to maintain consistency.

In the recent past, there've been a few changes to the rendering pipeline in the web engine. These changes have caused unexpected jumps in our benchmarks, even though there's no extra work being done during rendering. Most recent example: - PR: flutter#183791 - Regression reported in: flutter#184022 - Benchmark: [link](https://flutter-flutter-perf.luci.app/e/?begin=1773409816&enable_chart_tooltip=true&end=1774285808&keys=Xafc90b7a58b5e744fd23c4adf9bd5958&plotSummary=true&requestType=0&use_titles=true&xbaroffset=2806999) Previous example: - PR: flutter#180610 - Benchmark: [link](https://flutter-flutter-perf.luci.app/e/?begin=1767712957&enable_chart_tooltip=true&end=1768320686&keys=Xafc90b7a58b5e744fd23c4adf9bd5958&plotSummary=true&requestType=0&use_titles=true&xbaroffset=2806999) This PR fixes the issue by making our benchmarks handle asynchronous rendering correctly.
