When possible re-use the already allocated RX node for notifications.
Store (retain) RX node and Link element on RX if NTF could occur.
Pass link element to LLCP (ull_cp_rx()) together with RX node.
New RX node type RETAIN introduced to signal retention
When no RX node is available allocate one and hold off TX on procedures
until such time that a node is available for NTF.
In case waiting for NTF buffer avail is needed, allocate and store TX
node to use for TX once NTF becomes available.
CIS Established (incl. timeout handling) is now handled entirely as a
specific event driven by ull_conn_iso - ie removal of procedure check
of cis->established and cis->expire, as this is doubling mechanism
in the conn_iso context.
Unit test and helpers updated to handle new node type.
Function ull_cp_release_ntf() was used only in unit test, so moved to
helper context.
Updating release_ntf to handle the fact that with piggy-backing in test
context the node used for NTF can be from two different memory pools

Fix Extended Scanning support for BT_CTLR_LOW_LAT variant
of the Controller implementation by closing the scan window
for every ADV_EXT_IND PDU received that that ULL_LOW context
is enabled back and ticker job can process the request to
start auxiliary PDU reception. Without the change the
ticker job would only run at the end of the scan window that
caused the auxiliary scan prepare to assert due to delayed
ticker timeout expiry callback.

Fix AUX_ADV_IND AUX_SYNC_IND radio utilization by having a
configurable offset.
Define an offset between AUX_ADV_IND and AUX_SYNC_IND when
using Advertising Interval for the Extended Advertising and
Periodic Advertising that are same or multiple of each
other, respectively.
Note, to get advertising intervals that are same or
multiple, the Periodic Advertising Interval shall be 10
millisecond more than the Extended Advertising Interval;
this is because the AUX_ADV_IND PDUs are scheduled as
periodic events of Extended Advertising Interval plus 10
milliseconds (Advertising Random Delay) as the periodic
interval.

If CIS offset in LL_CIS_IND is less than EVENT_OVERHEAD_START_US, the
controller is not able to establish the CIS in the ACL connection event
specified, but needs to start setup one connection event earlier.
With this commit, if offset is larger than EVENT_OVERHEAD_START_US the
first CIS event can be prepared in due time immediately.
This enables the controller to setup first CIS, even when instant is
equal to the ACL event_counter.
