LibWeb: Skip backing store allocation for traversables created for SVG

Browse source 
Recently, we moved the backing store manager into Navigable, which means
we now try to allocate a backing store for all navigables, including
those corresponding to SVG image documents. This change disables that
behavior for all navigables except top-level non-SVG traversables,
because otherwise it causes issues when we stop repainting: the browser
process was notified about an allocated backing stores that does not
correspond to the page, and then all subsequent repaints are ignored
until the window is resized.
