latest PDU, then the offset should be filled into the latest

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.

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.

Fixes ticker_by_next_slot_get for JIT scheduler by allowing iterating
through ticker nodes without ticks_slot information, and improves
performance for legacy ticker scheduling use.
To reduce the processing and context switching overhead, a new feature
is introduced via BT_TICKER_NEXT_SLOT_GET_MATCH, by which an operation
callback may be added via the ticker_next_slot_get_ext interface, and
the match function is then called when the ticker_job is processing the
request.
By returning true in this callback, iteration stops and normal operation
callback is invoked. If the match function returns false, node iteration
continues. This reduces the number of ticker_job executions for node
iteration.

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_-

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.
