To ensure payloads are delivered in time for the first subevent
in framed BIS, ISOAL now enforces a (configurable) margin of
the calculated time offset
Without this margin, it has been observed that a broadcaster
can end up consistently missing the first subevent in every third
event in a 7.5 ms ISO with a 10 ms SDU interval
The margin is a conservative 2 ms by default, but can likely be
set a lot lower for most implementations and HWs

Introduces the concept of ll_scan_aux_chain, that allows for
keeping track of several advertising chains with a minimal
overhead. This replaces using several scan aux sets each with
an associated ticker IDs
Only one ticker is used for following chains; This is achieved
by having the scheduled chains in a sorted list and restarting
the ticker when the first in the list expires
EVENT_DONE_EXTRA_TYPE_SCAN_AUX now includes a pointer to the lll
structure to identify which chain to flush (to avoid race
conditions)
New implementation is hidden behind a config for now (defaults
to off): BT_CTLR_SCAN_AUX_USE_CHAINS
Other minor changes:
- rx_incomplete node pointer was moved to ll_sync_set
- data_len removed from ll_sync_set (it uses the chains instead)

Fix assertion when enabling simultaneous multiple Extended
Advertising chain reception that is enabled by increasing
supported auxiliary scan contexts.
ULL sets the association of aux context to scan and sync
context, and LLL resets the association; this is safer
compared to earlier implementation where ULL did both the
association and reset which caused aux context memory
leak.
Supported auxiliary scan contexts can be increased using
CONFIG_BT_CTLR_SCAN_AUX_SET value.

If a connection update (from central) overlaps a peripheral initiated
conneection param request, then central rejects peripheral request
and continues central procedure. This lead to an assert in peripheral
On instant there would not be an rx_node for notification, as this
would have been discarded by the reception of the REJECT.
This fix ensures that once an rx_node has been 'accepted' for retention
it will not be discarded/overwritten by future rx_nodes
The test will trigger the assert without the fix in.

This commit makes the device tree configuration decide
which link layer is compiled in. We do this to avoid
hard-to-understand linker errors referencing device tree nodes.
The following configuration creates a difficult to parse
linker error:
* BT_LL_CHOICE contains multiple entries, BT_LL_SW_SPLIT
is selected.
* Each BT_LL_CHOICE has its own unique device tree node with its
own "compatible".
* Only one of the link layer device tree nodes has status "okay",
but not the one corresponding to BT_LL_SW_SPLIT.
The linker error indicates that code using the HCI driver fails
to link with the controller. This because the HCI driver device
tree node references the link layer selected in devicetree which
is not compiled in.
By adding a dependendency to the device tree node, this can no longer
happen. Instead, if BT_LL_SW_SPLIT is now selected in a configuration
file, a Kconfig warning will be issued:
```
warning: The choice symbol BT_LL_SW_SPLIT
(defined at subsys/bluetooth/controller/Kconfig:129) was
selected (set =y), but BT_LL_SOFTDEVICE (defined at
/home/ruge/ncs/nrf/subsys/bluetooth/controller/Kconfig:11)
ended up as the choice selection.
```
This should be easier to understand than:
```
...(hci_core.c.obj):(.data.bt_dev+0x16c):
undefined reference to `__device_dts_ord_132'
```
After this commit we should consider getting rid of link layer
selection from Kconfig completely as the link layer is in practice
selected through device tree.
Unit tests have been updated to satisfy the dts dependency.

Fix Controller hang due to infinite looping caused by
duplicate node_rx enqueued in auxiliary context.
When LLL scheduling is not applied due to invalid aux offset
then ULL scheduling too would skip setting up the reception
after similarly checking the validity of aux offset required
to schedule the reception of auxiliary PDU. This check in
ULL was after the received node_rx being enqueued into the
auxiliary context causing a loop in the list of node_rx.
Dequeue of a list with a loop of node_rx caused an infinite
loop execution in the Controller.
