Zephyr kernel is dependent on trace. Trace is dependent on segger rtt. Segger rtt MUST NOT be dependent on zephyr kernel. Move lock functions from header into c file to avoid circular dependency. This fix needs an update of the segger repository. Fixes #43887. Signed-off-by: Christoph Coenen <ccoenen@baumer.com>
