Reviewed by Sihui Liu.

WebProcessProxy should use default settings values for near-suspended
assertions when they have no page. In WebKit, settings come from pages. The
WebProcessProxy therefore iterate through pages to figure out if it should take
near-suspended assertions and if it should drop them after a delay.

However, if the process doesn't have any pages, it would fall back to a value
that is not the default value for these settings, which would lead to
unexpected behavior in some case. This is particularly noticeable for service
worker processes which often don't have pages.
