Periodic advertising PDUs are now dispatched immediately one by one
(i.e. without list of PDUs as when flushed from aux context) so we
do not need to iterate such a list.

AdvA, TargetA, ADI and SyncInfo are RFU in periodic advertising PDUs so
we should ignore them when present in PDU.

Periodic advertising reports can be reated directly from single PDU
as they do not require any information from superior PDU, so we can
dispatch them immediately instead of buffering in aux context and
flushing at the end of chain.
This also resolves proper order of Periodic advertising and IQ reports.

We use 1st node enqueued in aux context to retrieve lll scan/sync
struct, but that only works if we buffer PDUs in aux context. It's
better to store parent lll struct as explicit member in aux context
as this also works if we skip buffering.

This adds complete support for scanning for periodic advertising trains.
AUX_SYNC_IND is always scheduled from ULL as usual, then code for aux
scanning is reused to allow for AUX_CHAIN_IND scanning scheduled from
both ULL and LLL, depending on AuxPtr.

aux->rx_last cannot be NULL since it's always set after acquire to a
valid node so the flow in flush() can be simplified.
rx parameter is only used to update PDU chain, then it's overwritten,
so we can instead update PDU chain in caller since there's only one
place when this should happen.

We should decide on flush immediately vs. from disabled_cb based on
ull_hdr reference count instead of last rxd node - if ull_hdr has
non-zero ref, then done event is still pending and we should flush
from there.

Make the block of code that is used to release node rx with
type NODE_RX_TYPE_RELEASE to be conditionally available for
other Kconfig selectable features like Extended Scanning.
Previously it was only available for CONFIG_BT_CONN, but now
Extended Scanning with LLL scheduling releases node rx when
radio event is closed due to failure to receive an auxiliary
PDU.
Relates to commit 2feffaf719 ("Bluetooth: Controller:
Release LLL scheduling aux on incomplete data").

Fix missing reset of connection handle in the LLL context.

ULL reference count is checked in ULL_LOW context to decide
if LLL events are pending, but the reference count can be
decremented by the ULL HIGH execution context which can
prevent the set `disabled_cb` function not being called due
to no pending event to produce the done events.
Fixed by checking the reference count in the ULL HIGH
execution context using a mayfly to schedule the check.
