This change introduces a `clip_gradients` option in `QtRule` and propagates it to the core quantization functions in `conv_general_qt`, `dot_general_qt`, and `ragged_dot_qt`. When enabled, this option causes gradients to be clipped during quantization, preventing values outside the calibration range from contributing to the gradient. The experimental `additional_qt_config` field has been removed. PiperOrigin-RevId: 824727722
