Reviewed by Geoffrey Garen.

Make it possible to set origin quota based on disk space. This is achieved by letting client specify a originQuotaRatio,
and using it to compute the quota: originQuota = totalDiskSpace * originQuotaRatio. If originQuotaRatio it is unset, we
will use perOriginStorageQuota for quota. By default, originQuotaRatio is unset.

Also, when quota is set using originQuotaRatio, quota increase will not be allowed (client will not receive delegate
callback about quota is exceeded).

To mitigate fingerprinting issue, StorageManager.estimate() might report a quota that is lower than actual qutoa when
usage is small.

Test: WKWebsiteDataStoreConfiguration.OriginQuotaRatio
