> This CL follows the [guide] to define a new permissions policy
> `deferred-fetch`, which is used to gate the new `fetchLater()` API.
> Relevant WPT are added in this CL, and the subsequent CL will further
> use this policy to adjust the request quota.
>
> In this CL, `deferred-fetch` is not added to chrome://settings/content
> page. And no permission prompt for it.
