Add Problem::EvaluateResidualBlockAssumingParametersUnchanged

Simplify the semantics for Problem::EvaluateResidualBlock to
not ignore the presence of EvaluationCallback and add another method
EvaluateResidualBlockAssumingParametersUnchanged to handle the case
where the user has an EvaluationCallback but knows that the parameter
blocks do not change between calls.

Updated the documentation for the methods and EvaluationCallback to
reflect these semantics.

Also added tests for Evaluation related methods calling i
EvaluationCallback when its present.
