Propagate destination through load_data (#37020)

This way, we don't always set the destination to Document (which is as
the spec is written today). Instead, we set it it in the load_data,
depending on which context we load it from.

Doing so allows us to set the `Destination::IFrame` for navigations in
iframes, enabling all frame-related CSP checks.

While we currently block iframes when `frame-src` or `child-src` is set,
their respective tests don't pass yet. That's because we don't yet
handle the cases
where we fire the correct `load` event.

Also update one WPT test to correctly fail, rather than erroring. That's
because it was using the wrong JS test variable.

Part of #4577
