Joshua Gross d269844cc1 LayoutAnimations: have each Props struct do its own interpolation
Summary:
Each ComponentDescriptor becomes capable of doing its own interpolation over props for animation purposes.

This new custom interpolator is called by default by the ConcreteComponentDescriptor, but `ComponentDescriptor::interpolateProps` is a virtual function and each ComponentDescriptor can provide custom interpolation if necessary.

For now, only View does any actual interpolation, to support LayoutAnimations.
