Add top-level creation URL for global scope (#37342)

Global scopes have two creation URLs: one for itself and one for the
"top-level" scope. It's not immediately obvious what is considered
top-level here (it is not strictly defined in the specification).

In any case, reports need the creation URL of the scope itself, not the
top-level version. Therefore, propagate this information from all
scopes, where the worker and worklets remain to pass in `None` for their
top-level scope.
