Address comments from Lasse in
https://dart-review.googlesource.com/c/sdk/+/331210. Namely:
* Use 100ms for the interval, so avoid overlap with the safety-margin of 40ms
* Rewrite comment to only discuss the safety margin in terms of an early
dispatch
* Only use the safety margin on web backends. Unlike timer_test, I am
using the presence of `dart.library.js` instead. Going forward it's
possible that dart2wasm hits this issue if it relies on browser's
timers.
I also copied the changes to lib_2 since flakiness is seen there too.
