Bug 1468946 [wpt PR 11525] - ES Modules: Set referrer for top-level module script in ModuleScriptLoader, a=testonly

Automatic update from web-platform-testsES Modules: Set referrer for top-level module script in ModuleScriptLoader

Before this CL, referrer for top-level module script is set in
BaseFetchContext::AddAdditionalRequestHeaders() using
ExecutionContext::GetOutgoingReferrer(). This works for documents, but doesn't
for workers because this execution context is corresponding to "module map
settings object", not "fetch client settings object".

To fix this, this CL sets the referrer for top-level module script using "fetch
client settings object" in ModuleScriptLoader as the spec defines.
