Fix grouping of console logs (#37835)

Summary:
Pull Request resolved: #37835

Chrome Dev Tools doesn't correctly display grouped console logs (i.e. console output between a `console.group` and `console.groupEnd`) when timestamps are all zero.

Populate the timestamp field so grouping functions as expected.

Changelog: [General] [Fixed] Fix timestamps and grouped display of console messages within in a `console.group`
