This CL improves the visualization of the Frames timeline such that frames are now demarcated with BeginFrame events instead of DrawFrame and DroppedFrame events. After this change, all visualized frames (both presented and dropped) are VSync-aligned and their durations are always multiples of 1/refresh rate. This new Frames timeline behaviour requires updates of some web tests, which were temporarily disabled by https://crrev.com/c/3197870 to allow the current CL to land.

DevTools frontend is also available on NPM as the chrome-devtools-frontend package. It's not currently available via CJS or ES modules, so consuming this package in other tools may require some effort.
The version number of the npm package (e.g. 1.0.373466) refers to the Chromium commit position of latest frontend git commit. It's incremented with every Chromium commit, however the package is updated roughly daily.
