Bluetooth: controller: Add per sync filt by CTE type for SOC w/o DFE

First implementation of periodic advertising sync filtering
requires existence of Direction Finding Extension in Radio
peripheral.
To add the filtering support for other Nodric SOCs software
based PDU traversing for CTEInfo should be implemented.

In case there is no DFE in Radio peripheral, actual filtering
is done in ULL.

The commit provides necessary changes to previous solution.
