Other information

This builds on scheduler.postTask(), which I know has been prototyped but not shipped in Gecko. We recently landed WICG/scheduling-apis#92 to try to address concerns captured in WICG/scheduling-apis#67. That same concern will apply to this API, which builds on the existing prioritization in the spec.

I think the task ordering can still be discussed, but generally we are positive for this.

https://mozilla.github.io/standards-positions/#scheduling-api entry exists, this is an addition. No new entry needed.
