Added the option of using rotationally symmetric expressions in KPP_smooth_BLD(). This is enabled by setting the new runtime parameter KPP%ANSWER_DATE to a value of 20240501 or higher. For now the default is to use the older symmetry-breaking expressions, but the default value for KPP%ANSWER_DATE should be revised to use DEFAULT_ANSWER_DATE. By default, all answers are bitwise identical but there is a new entry in some MOM_parameter_doc files.
