\brief Copy an optimization context from a source to a target context.
This function allows translating an optimization context from one Z3_context
to another. This is useful when working with multiple contexts and needing to
transfer optimization problems between them.
\param c Source context containing the optimization context to translate
\param o The optimization context to translate from the source context
\param target Target context where the optimization context will be created
\return A new optimization context in the target context with the same state
