Updating input handling in WF optimizer

[markdewing]

Convert WF optimizers to use input handling similar to VMCDriverInput.

This will separate XML processing from the classes that use the input parameters.

One class was addressed in #3144 - QMCOptimizeBatched

Other classes that need to be done:

• QMCFixedSampleLinearOptimizeBatched - this has a large number of parameters from the quartic method. I think we will need to divide up the parameter between the quartic method, the single shift run, etc.
• QMCCostFunctionBase - might do this after combining QMCCostFunctionBatched/QMCCostFunctionBase
