Follow up on changes in lower link layer to add filtering
of periodic advertisements synchronization by CTE type.

The NODE_RX_TYPE_SYNC is used to transport information that:
- Sync is established. In such situation the node_rx
  includes data related with received PDU
- Sync scanning is terminated.
In first case ULL will generate NODE_RX_TYPE_SYNC_REPORT
after sending NODE_RX_TYPE_SYNC.

Also EVENT_DONE_EXTRA_TYPE_SYNC handling has additional
execution path that terminates sync scanning if requested
by lower link layer. In other case it adjusts sync scan
window and maintains timeout as usual.
