Explicitly includes IGraphicBufferProducer.h in gui/view/Surface.h

When using android.view.Surface in an AIDL file as below:

---
package my.package;

import android.view.Surface;

interface IFoo {
     Surface getInputSurface();
}
---

and Cpp backend is enabled, the auto-generated Cpp files
will not be compiled successfully.

In file gui/view/Surface.h, it uses class forward declaration of
IGraphicBufferProducer, but IGraphicBufferProducer.h is not included
anywhere else, so the compiler does not know what
IGraphicBufferProducer actually is, especially the inheritance
relationship between IGraphicBufferProducer and RefBase, finally, it
stops and prints out the following error:
