SVM sigmoid kernel fix (issue #13621) (#13718) * Added test for sigmoid case for retrieving support vectors * undo unhelpful test * add test for sigmoid SVM with data that is easily separable into two concentric circles * Update sigmoid kernel to use tanh(gamma * <x, y> + coef0) instead of -tanh(gamma * <x, y> + coef0) * remove unnecessary constraint on coef0 * cleanup * fixing inappropriate use of doubles * Add f to float literal * replace CV_Assert with ASSERT_EQ where appropriate

In case of regression trees, node risk is computed as sum of squared error. To get a meaningfull value to compare with it needs to be normalized to the number of samples in the node (or more generally to the sum of sample weights in this node). Otherwise the sum of squared error is highly dependend on the number of samples in the node and comparision with `regressionAccuracy` parameter is not very meaningful. After normalization `node_risk` means in fact sample variance for all samples in the node, which makes much more sence and seams to be what was originaly intended by the code given that node risk is later used as a split termination criteria by ``` sqrt(node.node_risk) < params.getRegressionAccuracy() ```

This is at least useful when using an SVM one-class linear classifier, so there are valid use cases.
