cc: Avoid duplicate work when computing draw properties using property trees

This adds a ComputeLayerDrawPropertiesUsingPropertyTrees function and a
ComputeSurfaceDrawPropertiesUsingPropertyTrees function that compute
these properties together, avoiding re-computing values that are needed
by the computation of more than one property.
