Fix float classes

[tom-hg57]

Recognition as Float for C++/Java is not correct for some classes and attributes:

• Some CGMES_2 classes has to be recognized as float, e.g. ActivePowerPerFrequency. These classes contain only a simple float value. All other attributes (multiplier, unit, denominatorMultiplier, denominatorUnit) are fixed.
• For CGMES_3 the Float class itself has to be reconized as simple float to prevent that it is treated as pointer to an object, e.g. position in SvTapStep.
