Original change's description:
> Prerender: Pass SpeculationRulesTags up to PrerenderHost
>
> This is a preparation for supporting Speculation Rules tags for
> prerendering. This CL passes SpeculationRulesTags from PrerenererImpl to
> PrerenderHost, so that follow-up CLs can add the Sec-Speculation-Tags
> HTTP header based on that.
>
> PrerendererImpl passes other Speculation Rules specific parameters like
> the target hint and the eagerness. For code simplification, this CL
> bundle them into SpeculationRulesParams struct and also adds
> SpeculationRulesTags into the struct.
>
> This CL changes SpeculationRulesTags from movable-only to
> copyable-and-movable, as its owners (PrerenderAttributes and
> SpeculationRulesParams) can be copied.
