Andreas Kling 31ffb2f214 LibWeb: Use the id cache for document element get_element_by_id() 
ParentNode::get_element_by_id() only used the cached id-to-element map
when called on a document or shadow root; on any element it fell back
to a linear walk of the subtree. The document element's inclusive
subtree contains every element in the document, so the document's
cache gives the same answer.

This matters because SVGSVGElement::children_changed() resolves the
document URL fragment with get_element_by_id() on itself whenever the
document URL has a fragment. SVG sprite sheets are typically fetched
via URLs like sprite.svg#icon-name, and the sprite's outermost svg
element is its document element, so every child appended during
parsing rescanned the growing document. These lookups were 2.3% of
all CPU samples when loading chatgpt.com.
