     * When resolving the calleeExpression of a `KtCallExpression`, we resolve the entire `KtCallExpression` instead. This way, the
     * corresponding FIR element is the `FirFunctionCall`, etc. Implicit invoke is then specially handled after obtaining the
     * `FirImplicitInvokeCall`.
     *
     * Note that, if the calleeExpression is already a KtCallExpression, then we don't do this because such a callExpression can be properly
