Bluetooth: Controller: Integrate CTE req in ULL with refactored LLCPs

Browse source 
Integrate existing CTE request control procedure code in ULL with
implementation of refactor LLCPs.
The commit includes code responsible for:
- enabling CTE request and scheduling its execution by refactored
  LLCPs framework,
- running CTE request periodically
- disabling CTE reqest in case it is running periodic
