Revert "Rewrite hr-timestamp/input-events.html to a browser test" 

This reverts commit 4f6da930.

Reason for revert: InputEventBrowserTest.TouchStartEventTimeStamp is flaky in android pie CQ builder: https://analysis.chromium.org/p/chromium/flake-portal/flakes/occurrences?key=ag9zfmZpbmRpdC1mb3ItbWVyVwsSBUZsYWtlIkxjaHJvbWl1bUBjb250ZW50X2Jyb3dzZXJ0ZXN0c0BJbnB1dEV2ZW50QnJvd3NlclRlc3QuVG91Y2hTdGFydEV2ZW50VGltZVN0YW1wDA

It is flaky in several waterfall builders as well, starting at
https://ci.chromium.org/p/chromium/builders/ci/android-pie-x86-rel/1565
https://ci.chromium.org/p/chromium/builders/ci/android-pie-arm64-rel/5952
https://ci.chromium.org/p/chromium/builders/ci/android-asan/7107

Original change's description:
> Rewrite hr-timestamp/input-events.html to a browser test
> 
> hr-timestamp/input-events.htmlEvent timestamp tests that the received
> events on the page should be equal to the timestamp provided by the
> eventSender's recorded last event. But we should deprecate eventSender in
> the future, and GpuBenchmarking sends events based on the current system
> time, which cannot be equal to the received events' timestamp.
