gfx: Improve handle management in gfx::GpuMemoryBuffer The handle returned from gfx::GpuMemoryBuffer::GetHandle() is either passed to CloneHandleForIPC immediately or used to obtain some handle metadata (type, GUID). This CL replaces GpuMemoryBuffer::GetHandle() with the new method GpuMemoryBuffer::CloneHandle() that is equivalent of calling CloneHandleForIPC(buffer.GetHandle()). This will allow to use scoped objects for all types of underlying platform handles, since no two GpuMemoryBufferHandles will refer to the same system resource. New methods are also added to access type/GUID of buffer. As a demonstration, this CL changes the type of the GpuMemoryBufferHandle::android_hardware_buffer from AHardwareBuffer* to base::android::ScopedHardwareBufferHandle.
