This commit enables channel manager on SSED, together with channel monitor, auto-selecting a better CSL channel for the link between child and its parent. It also fixes tracking of CcaSuccessRate on CslChannel and adds toranj tests for auto-channel selection and thread_cert test for autocsl-channel selection.
