scorpion-26 d00adabc3c LibWeb: Preserve order of HTMLCollection property names
The supported property names should be ordered in "tree order", though
m_cached_name_to_element_mappings doesn't preserve this ordering, which
breaks Object.getOwnPropertyNames.

Fixes at least the following WPT tests:
 - https://wpt.live/dom/nodes/Element-children.html
 - https://wpt.live/dom/collections/HTMLCollection-live-mutations.window.html
 - https://wpt.live/dom/collections/HTMLCollection-supported-property-names.html
