Truncate "meanCount" and "stdCount" results

[fabioh8010]

Summary

Some component (example: AsyncComponent.tsx) can have different render counts due to its nature or behavior during tests. Currently these difference in render counts between baseline and delta will lead to decimal meanCount and stdCount results, which don't quite make sense since we are talking about renders (there are no "decimal" renders). This PR fix the result data by truncating these properties.

Test plan

Make sure unit tests pass.

Let's not do it, rather we should apply outlier removal to render count as well (now we only do it only to render durations).
