After extracting from ull_adv_sync_pdu_set_clear functions:
ull_adv_sync_pdu_alloc, ull_adv_sync_extra_data_set_clear
Use of ull_adv_ext_hrd_data structure became unnecessary.
The extra_data member of the structure was never used
due to separate function responsible for setting extra_data
content.
In all cases content for extended advertising header fields
may be passed to the ull_adv_sync_pdu_set_clear directly
as void * pointer, instead of pointer to ull_adv_ext_hdr_data.
This simplifies use of ull_adv_sync_pdu_set_clear as well
as removes unneccesary code to handle special structure type.

ull_adv_sync_pdu_alloc function was extracted from ull_adv_sync_pdu_-
-set_clear function. The arguments list of ull_adv_sync_pdu_alloc
was derived from source function but the acutal functionality is
only part of what it was before.
The ull_adv_sync_pdu_alloc does not change extended advertising
PDU header fileds. The hdr_add_fields and hdr_rem_fields arguments
were used to allocate or not allocate memory for extra_data related
with new periodic advertising PDU. Also hrd_data pointer was
not used by the function.
The function arguments list was simplified.
New enum ull_adv_pdu_extra_data_flag was introduced to provide
named flags for extra_data memory management.

There was an issue with wrong length of CTE send in connectionless
mode, with periodic advertising PDUs. Radio peripheral was not
configured to send CTE with correct length while PDU had CTEInfo
field informing receiver that CTE is attached to the PDU.
Source of the problem was in ll_df_set_cl_cte_tx_enable function.
Order of parameters in ull_adv_sync_pdu_alloc was wrong.
ULL_ADV_PDU_HDR_FIELD_CTE_INFO was speficed as hdr_rem_fields.
Because of that extra_data, memory used to provide CTE configuration
to LLL, was not allocated. PDU content is prepared in ULL, so CTEInfo
field included correct information, while Radio was never configured
by LLL to send CTE.
ull_adv_sync_extra_data_set_clear received a pointer to hdr_data,
instead of a direct pointer to df_cfg structure. When extra_data
was allocated correclty, wrong CTE configuration was provided
copied there and LLL received invalid CTE length. It was different
than the length in PDUs CTEInfo field.
