Reviewed by Youenn Fablet.

According to spec (https://storage.spec.whatwg.org/#introduction), an origin can request to be persistent with
StorageManager.persist(), which means its data will be exempt from eviction on storage pressure. This patch implements a
rule to decide whether an origin can be persistent.

Test: WKWebsiteDataStoreConfiguration.TotalQuotaRatioWithPersistedDomain
