SWPROT-9242: Move s2 protocol CC encryption handling to protocol CC

- create a protocol command class handler that handle also protocol LR
  commands
- add unit tests for this handler
- remove request protocol cc encryption code from s2 and move it to new
  protocol cc
- add supervision encapsulation of protocol cc
