Shannon Booth 9d729e19bf LibWeb: Rename SharedImageRequest to SharedResourceRequest
For the SVG <use> element, we want to support loading HTML documents
that have a SVG element inside of it pointed to by the URL fragment.

In this situation we would need to fetch and parse the entire document
in SharedImageRequest (so that we can still cache the SVGs). Rename
SharedImageRequest to SharedResourceRequest to make the class a little
more generic for future usecases.

(cherry picked from commit a342370dfb4f1eeabc7dcb8fbe6f8e4eb6f6b1f4)
