Forward declare? (Chromium style diverges from google3 style)

It doesn't seem to provide any benefit in this leaf include file,
but here you go.

+#include "content/public/browser/web_contents.h"
+#include "mojo/public/cpp/bindings/binding.h"
+
+class PaymentRequestImpl : blink::mojom::PaymentRequest {
+ public:
+  PaymentRequestImpl(
+      content::RenderFrameHost* render_frame_host,
+      content::WebContents* web_contents,
+      mojo::InterfaceRequest<blink::mojom::PaymentRequest> request);
+  ~PaymentRequestImpl() override;
+
+  // payments::mojom::PaymentRequest "stub"
+  void Init(blink::mojom::PaymentRequestClientPtr client,
+            std::vector<blink::mojom::PaymentMethodDataPtr> methodData,
+            blink::mojom::PaymentDetailsPtr details,
+            blink::mojom::PaymentOptionsPtr options) override;
+  void Show() override {}

Not sure if the compiler will like the impl for virtual methods in the header.
Run some try jobs?

I haven't seen any complain.
