networkException 5aa7c51956 LibWeb: Pass around JS::HeapFunctions when fetching scripts
This patch replaces the use of JS::SafeFunction for the
OnFetchScriptComplete in various script fetching functions with
JS::HeapFunction. The same applies for callbacks in ModuleMap.

This also removes DescendantFetchingContext, which stashed the
on complete function in fetch_descendants_of_a_module_script
for multiple calls to fetch_internal_module_script_graph
previously.
