[js_runtime, js_dev_runtime] Implement `microsecond` field of `DataTime`

- Move DateTime implementation for dart2js and DDC into a shared place to reduce duplication.

- Add a _microsecond field to the web DateTime to track microseconds outside of the JavaScript Date.

- The cute dart2js optimization whereby `DateTime.now().millisecondsSinceEpoch` is compiled to `Date.now()` still works.

- Both implementations report better errors.

- Fixed VM bug with in-range sentinel.
