Deprecate blink::mojom::ResourceType in PluginResponseInterceptorURLLoaderThrottle

This CL replaces blink::mojom::ResourceType with
network::mojom::RequestDestination in
PluginResponseInterceptorURLLoaderThrottle since
blink::mojom::ResourceType is deprecated[1].

It replaces |resource_type_| with |request_destination_| in
PluginResponseInterceptorURLLoaderThrottle and uses it to
check if the request is for the main frame.
