Piotr Pryga 26a66ee299 tests: Bluetooth: df: Fix not building unit tests 
There were changes done to controller code that cause
tests to do not build and fail during execution.
Changes are related with:
- modified code related with extended advertising ADI
  field handling
- added generic double buffer data structure that is
  used in controller
- moved code that was building only when DF is enabled
- added EVENTS_PHYEND that is not available in nrfbsim
  board

The PR addresses those issues.
