Add support for (de)serializing HeadsUpDisplayLayer

Add support for (de)serializing HeadsUpDisplayLayer

They LayerTreeHost has a HUD-layer as a member, and as part of the
CL for adding support for (de)serializing the LayerTreeHost,
the test code incorrectly creates a cc:Layer instead
of a cc:HeadsUpDisplayLayer, and this is not checked.

The Linux CFI bot luckily caught this error, so this CL fixes
the error by adding support for the layer type.

The HUD layer has no special members, but do have some special logic
for drawing, so only the type needed to be serialized.
