layout: Parameterize content box query (#38935)

Browse source 
Parameterize and rename both `Layout::content_box_query` and
`Layout::content_boxes_query` to support the query of rendered padding
area and content area that accounts for transform and scroll. Both of
these query have been misleading for a time since they are using border
box, instead of content box of a Node.

This PR adds a new type `layout_api::BoxAreaType` to be passed from
`ScriptThread` to `LayoutThread` to query the respective area. It is
then used for the query within `IntersectionObserver` to pass several
WPTs.

Testing: Existing WPT Coverage.
