Fix broken forward declaration that introduced a clashing namespace

A forward declaration claimed there was a ::viz::cc:CompositorFrame
class, and that introduction of a namespace ::viz::cc caused
confusion with the ::cc namespace and compilation errors in
some jumbo build configurations.

The real CompositorFrame is in viz::CompositorFrame so fixing
the forward declaration also removed the namespace clash.
