Shared Storage: Support saved queries in selectURL (#48868)
We add support for saved queries, keyed by
(data_origin, script_url, operation_name, query_name).
When a named query is first invoked, the per page budgets are charged
as usual, the index result is stored for later in case the query is
reused from the same page.
On query reuse, the previously calculated and stored index result
will be used to select the URL at that index in the current list, and
the per page budgets will not be re-charged.
When the page is destroyed, all associated saved queries are also
destroyed.
