The filtering of periodic advertisements by scanner may be not needed
in certain situations e.g. while use of periodic advertising by BT ISO.
To make the code smaller and avoid execution of not needed code the
functionality will be conditionally compilable. It may be enabled
or disabled by use of CONFIG_BT_CTLR_SYNC_PERIODIC_CTE_TYPE_FILTERING
Kconfig option.

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.

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.

As EVENT_OVERHEAD_START_US offset is used in ticks unit in
LLL, ULL scheduling using ticker should also use ticks unit
for EVENT_OVERHEAD_START_US when reducing the first

Change use of dedicated memory pool for linked list nodes for
node_rx_iq_report to common mem_link_rx. Former solution had
a drawback. Released link nodes may be enqueued to wrong memory
pool. E.g. link related with nopde_rx_iq_report went to common
link memory pool, whereas link nodes from common pool were enqueued
to dedicated list.
The solution was working because links have the same memory layout,
just different memory pools they originated from.
The problem may occur if one of those link memory pools is reset.
Then the same link may be used by node_rx and node_rx_iq_report
at the same time, causing controller failure.

Avoid using sizeof to access ULL and LLL struct members.
Based on the alignment requirements of structures, due to
padding between structure members, use of sizeof of previous
struct member to access next struct member is incorrect.
Continue to use explicitly stored parent pointer to access
ULL context. Combine event header and ULL header so that
the parent pointer point directly to the combined ULL
struct.
