Remove LL_ASSERT from functions that return latest advertising PDU.
The LL_ASSERT was raised in situation that there is no memory to
store unused PDUs memory in a pdu_free queue or extra_data_free queue
Those functions return NULL in such sitation. The returned value is
verified by callers by LL_ASSERT. That gives better context if lack
of memory issue issue occurs.
Besides that there was removed a LL_ASSERT from lll_adv_pdu_and_extra_-
data_alloc. The reasons is the same as above, to give better context
when the lack of memory issue occurs.
This function is used in ULL context (ll_adv_sync_ad_data_set).
If it returns NULL the caller will return BT_HCI_ERR_MEM_CAPACITY_-
EXCEEDED to Host.

Add set of functions that will make possible to configure
radio Direction Finding Extension to transmit CTE for periodic
advertising.
Some of the new Radio API functions are provided as separate
functions changing the same Radio peripheral registers, e.g.
radio_df_mode_set_aoa, radio_df_mode_set_aod. This is done on
purpose and is related with lack of DFE in nrf52_bsim.
To avoid use of conditionally compiled constants to represent
e.g. CTE mode; separate functions were introduced.
Thanks to that DF unit tests are able to compile successfully
without changes in nrf52_bsim platform. Also if DFE is added
to nrf52_bsim there is no need to change the code until it is
desired.

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.

The problem was, in an encrypted connection the enqueued PDU

while encryption completed into the encrypted buffer.

Fix error introduced by pull request:
https://github.com/zephyrproject-rtos/zephyr/pull/31591
Zephyrs CMake extension function zephyr_library_sources_ifdef()
does not allow to use complex conditions to toggle if
sources should be included in build or not.
It allows to use only single variable as an input for
feature_toggle argument because it is double-expanded
in contition statement in the function.
In case there is a requirement that source file is included
when more complicated condition is true we have to fall-back
to reqular if() statement and zephyr_library_sources().
The fix is required because without it radio_df.c source
is never compiled. If DF functionality is enabled build
will fail because of missing functions implementation.
