Add DynamicNumericDiffCostFunction.

This brings the ability to have numerically differentiated
cost functions to be added with its structure decided on
runtime rather than compile time.

And some minor cleanups.

Two things still need to be done.

a. Update the modeling docs.
b. Remove RuntimeNumericDiffCostFunction in ceres::internal
   and replace its usage with DynamicNumericDiffCostFunction.
