migration to NCS 2.7

[tongli-dev]

Thank you for the great demo.

We are migrating to the latest NCS v2.7. The ESB library has changed, and the function RADIO_IRQHandler(void) has disappeared. It seems to be replaced by static void radio_dynamic_irq_handler(const void *args). However, this function cannot be called during the MPSL_TIMESLOT_SIGNAL_RADIO event.

What would be the proper way to call radio_dynamic_irq_handler without modifying the SDK?
