blink::WebEmbeddedWorkerImpl used to override interfaceProvider method - we just
inline the body of the old method (getting the interface provider from the
current platform) above.

blink::WebEmbeddedWorkerImpl did not override interfaceRegistry method - it just
inherited the default implementation from blink::WebFrameClient which used to
return nullptr.
