Remove prefixes in classes and enumerations

[jorgepiloto]

🐞 Problem

Prefixes such as IAg, IAgVA (among others) are no longer required.

Some objects may be affected when removing the prefix, leading to non valid Python syntax. For example, removing the prefixes in the enumeration and applying naming conventions AgEVePropagatorType.ePropagator11Param leads to PROPAGATOR_TYPE.11_PARAM, which is not allowed in Python syntax, since the enumeration item starts with a number.

Particular cases need to be applied and documented.
