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.

Disable of CTE sampling for periodic advertising sync PDUs may be
interrupted by radio event. In such situation, TX thread will be
handled before RX thread delivers IQ samples report to host. In
this case RX thread would deliver IQ samples report after CTE
sampling was disabled.
To avoid such situation RX thread has to check if:
- CTE sampling is not disabled,
- CTE sampling was not requested to be disabled after start of radio
event.
CTE sampling configuration is double buffered. Updated configuration is
swapped at the beginning of radio event.
If CTE sampling is diabled or requested to disable (next radio event
didn't start), the IQ samples report should be dropped by RX thread
and should not be delivered to host.

Add new kind of node_rx type that will store IQ samples report.
The structure includes node_rx_hdr and may be used by the same
queues that are used to forward regular node_rx_pdu objects
between LLL and ULL.

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.

The storage for extra data is required for implementation of
CTE transmission with periodic advertising.
Data required to transmit CTE correctly are compound of two parts:
- PDU field CTEInfo
- radio configuration to transmit actual constant tone at the end
of PDU.
Extra data is a storage required for radio configuration data.
Nevertheless it must be in compliance with content of CTEInfo field.
Because of that extra data is stored as part of lll_adv_pdu and
is double buffered like PDU memory.
Bluetooth 5.1 spec. allows to enable or disable CTE TX
and change CTE TX parameters when periodic advertising is
enabled. Besides that CTE TX settings may be set before periodic
advertising parameters are set. In such situation ll_adv_sync_set
may be not yet created.
To overcome these constraints ULL should store CTE TX
settings and forward them to LLL only when CTE TX is enabled.
Because of above reasons ULL stores CTE TX settings in ll_adv_set.

Fix compilation error if CONFIG_BT_CTLR_DF is not defined.
If DF was not enabled, there was missing CONFIG_BT_CTLR_DF_MAX_-
ANT_SW_PATTERN_LEN and undeclared symbol was found.
Split ll_df.h into two parts:
- ll_df.h that is generally includeable and allows to successfully
compile sources when DF is not enabled.
- ll_df_internal.h to be used in soucres that are compiled when
DF is enabled.
