net: openthread: allow to configure CSL debugging

Browse source 
Add new `IEEE802154_CSL_DEBUG` Kconfig option that, when enabled,
prevents the radio to sleep after a delayed reception is finished.

This allows to debug CSL timing issues due to accuracy drifts in
communications between receiver and transmitter.
