[NPU] Introduce a config option that specifies the version of the VCL serializer to be used

[razvanapetroaie]

Details:

• The current boolean option that switches between the two implementations will be discarded in favor of this newer enum-based one. This type of data will allow us to patch the current implementation and handle compatiblity cases in a custom manner.
• To facilitate migration, only the option supported by the compiler will be registered in the config object (if set explicitly). So the flow is: check the value used by use_base_model_serializer (this one has priority) or model_serializer_version -> store the value and remove the options before building the config -> write in the config only the option supported by the compiler.
