Direction finding functionality allows to send a number of periodic
advertising PDUs in a chain that have CTE.
ll_df_set_cl_cte_tx_enable function was changed to update periodic
advertising chain to include cte_info field. If the chain is too short,
there is less PDUs in the chain than requested number of CTEs,
the function will add new empty PDUs to the chain end.

Enabling or disabling transmission of Constant Tone Extension with
periodic advertising PDUs requires update of a PDU content.
CTE_INFO field of periodic advertising PDU must be filled with
appropriate data. That operation may be done for periodic
advertising PDU (or chain of PDUs) filled with other payload that
wasn't enqueued towards LLL. In that situation PDUs are updated
in place, to avoid increase of memory consumption.
The commit changes ull_adv_sync_pdu_set_clear function to
make possible update of the advertising PDU in place.

Add configuration of CTE for periodic advertising chain transmission.
The commit provides configuration of radio in prepare stage and
in handle of Tx ISR. CTE is configured only for PDUs that
have cte_info field in extended advertising header.
During prepare of periodic advertising event there are updated
aux_ptr fields in extended advertising header in other PDUs from
a periodic advertising chain. aux_ptr offset value also depends
on CTE length. CTE configuration is always the same for every
PDU in periodic advertising chain.
CTE may be added to requested number of PDUs in periodic
advertising chain. Although it is possible that there are PDUs
that don't have CTE. PDUs that have CTE are alsways at the beginning
of a periodic advertising chain.

Configuration of CTE for transmission is stored in extra_date member
of a lll_adv_sync object. PDUs in periodic advertising chain share the
same CTE configuration, so there is single instance of the extra_data.
To configure CTE transmission for every PDU in periodic advertising
chain a new function was introduced to peek extra_data instance without
peeking new PDU.

Transmission of Constant Tone Extension is done after END event
triggered by radio. To correctly switch from TX to TX (back 2 back
TX) after transmission of CTE PHYEND event must be used instead of
END event.
The commit provides required function that allows LLL to correctly
setup radio to do back to back switch of TX when CTE transmission
is enabled.
The radio_switch_complete_and_phy_end_b2b_tx cannot be implemented
in radio.c source file. It will fail build of unit tests targeted
for NRFBSIM simulator board. There is no RADIO_SHORTS_PHYEND_DISABLE_Msk
macro defined in bsim_hw_models module.

Amount of memory allocated for advertising PDUs (including
periodic advertising) depends on two factors:
- maximum advertising data length
- maximum number of CTE in a periodic advertising chain.
Maximum advertising data length is divided by maximum size
of a single fragment (number of payload bytes that single
advertising PDU may hold) to get required number of fragments.
Actual number of PDUs allocated for advertising is maximum
of acutal number of advertising payload fragments and maximum
number of CTEs.

The existing extension tree does not support all the features that are
defined by the specification (e.g. multiple parents).
This patch approaches this problem by defining a circular single-linked
list of extension models. So for a given model, all models that are on
the same list as that model are in some extension relationship with that
model. All models on a list represent a single connected component of an
extension graph but without defining specific relationships between each
pair of models. This list is used to manage a shared subscription list
as per the Mesh Profile Specification:
```4.2.4 Subscription List
Within an element, each model has a separate instance of a Subscription
List, unless the model extends another model on that element. Instances
of models that extend other models (i.e., all models within an extension
relation tree) shall share a single instance of a Subscription List per
element.

The Bluetooth Core spec 5.2 requires to provide CTE type in
periodic advertising report.
The implementation of le_per_adv_sync_report assigned
value zero to be default CTE type. The assigned value
in Bluetooth Core spec 5.2 means "AoA Constant Tone
Extension". In case there is no CTE attached to periodic
advertising PDU, CTE type should contain value 0xFF.

There was an issue with receiving CTE packets when the time
slot has changed from 2us to 1us. After receiving the packets
when it tries to enable receiving of CTE, the validator
returns EINVAL error.
Source of the problem is "validate_cte_rx_params" function,
it calls DF_AOA_RX_1US_SUPPORT(df_ant_info.switch_sample_rates)
which is expanded to:
((df_ant_info.switch_sample_rates) & BIT((BT_HCI_LE_1US_AOA_RX)))
And due to definition of BT_HCI_LE_1US_AOA_RX in hci.h it will be:
((df_ant_info.switch_sample_rates) & BIT(BIT(2)))
So the BIT operation has executed two times.
