Fix double prepare overhead considered in scheduling
extended, periodic and ISO broadcast radio events when using
LOW LAT variant.
ticks_slot maintained in ticker includes the overhead, the
ticks_slot stored in role/state context exclude the overhead
hence take care to include ticks_slot_overhead when value is
used from context and not when value used from ticker nodes.
Add jitter due to ticker resolution unit between scheduled
radio events. This will allow the synchronizing side too to

Fix ull_prepare_dequeue to not skip events when preempt
does not match the event in the head of the prepare queue.
The head of the prepare queue does not match when
ull_prepare_dequeue has put the head of the queue to the
last of the queue when it is calling lll_resume interface.
This happens when there is already an active event which
needs a preempt timeout to be setup and there is another
non-resume event in the pipeline which now becomes the
head. The fix ensure to restore the order of the events
if a preempt timeout was to be setup.
Currently ull_prepare_dequeue loops through all events
before stopping at the original way the queue was. This is
not efficient and is a scope for improvement in future.
This reverts commit 91781306e9 ("Revert "Bluetooth:
Controller: Fix ull_prepare_dequeue for skipped events"").

If an instant based remote procedure 'overtakes' a local ditto
the local procedure will be 'completed' by remote rejection
but collision flag would not get set ensuring that a new local
conflicting procedure cannot be started before the remote is completed.
This can thus lead to invalid local initiation.
Added unittest to cover case
Fix by ensuring collision flag is set also in the above mentioned
scenario.

radio_pkt_big_ctrl_get() returns a statically allocated
buffer of type pdu_big_ctrl, but the callers expect a
buffer where a whole PDU for a BIG control packet can fit
(not just space for the payload),
and use it as such, overflowing this statically
allocated buffer, and smashing other variables after.
Let's fix it by allocating a buffer of the correct size
to fit a BIG control PDU.

BT_CTLR_ISOAL_LOG_DBG_VERBOSE, BT_CTLR_ISO_TX_SEG_PLAYLOAD_MIN, and
BT_CTLR_CONN_ISO_AVOID_SEGMENTATION are very tied to the BT_LL_SW_SPLIT

another controller
Therefore move them out to the BT_LL_SW_SPLIT specific configuration
file. This will likely create less confusion when using another
