Reland "service worker: Use mojo version of GetUserDataForAllRegistrations"

This is a reland of 853e0dd9

The original CL was reverted due to a data race. The race was fixed
in crrev.com/c/2340297

Original change's description:
> service worker: Use mojo version of GetUserDataForAllRegistrations
>
> This CL starts using mojo version of
> GetUserDataForAllRegistrations{,ByKeyPrefix}().
>
> The type of the return value of these methods is also changed from
> map<registration_id, value> to array<ServiceWorkerUserData>,
> and ServiceWorkerUserData now has registration_id.
> These changes are required to handle a situation where a
> registration_id is associated with multiple values. Some features like
> payments could associate multiple values for a registration_id.
