integrate scheduler.yield in SchedulerPostTask (#27069)

## Summary

`scheduler.yield` is entering [Origin Trial soon in Chrome
115](https://chromestatus.com/feature/6266249336586240). This diff adds
it to `SchedulerPostTask` when scheduling continuations to allow Origin
Trial participation for early feedback on the new API.

It seems the difference here versus the current use of `postTask` will
be minor – the intent behind `scheduler.yield` seems to mostly be better
ergonomics for scheduling continuations, but it may be interesting to
see if the follow aspect of it results in any tangible difference in
scheduling (from
[here](https://github.com/WICG/scheduling-apis/blob/main/explainers/yield-and-continuation.md#introduction)):

> To mitigate yielding performance penalty concerns, UAs prioritize
scheduler.yield() continuations over tasks of the same priority or
similar task sources.

## How did you test this change?
