Add placeholder implementation of DOM `VisualViewport` according to the spec https://drafts.csswg.org/cssom-view/#visualviewport. This is the first step of implementing the interface and syncing it with the `PinchZoom` struct that we had in the `Embedder`. Since this interface's is not accurate and couldn't fulfill it's purpose, it would be gated behind a preference `dom_visual_viewport_enabled` and would be open after the interface had been integrated with `PinchZoom`, viewport resizing, and viewport scroll. Testing: Existing WPT Test. Part of: #41341 --------- Signed-off-by: Jo Steven Novaryo <steven.novaryo@gmail.com>
