Add a size parameter to SharedMemoryHandle.
This is needed to construct a Mojo shared buffer from a SharedMemoryHandle,
which in turn is needed to pass GUIDs through Mojo. Previously, classes like
gfx::GpuMemoryBufferHandle were being serialized as a file descriptor or Windows
HANDLE, rather than a SharedMemoryHandle because they did not have access to a
size field.
