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").

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.

This patch is the first step to make the rpmsg_multi_instance usable in
a multi-core scenario.
The current driver is using a local driver variable (instance) to track
the number of allocated instances. This counter is practically used to
allocate to the instance the correct portion of the shared memory.
This is fundamentally wrong because this is assuming that it does exist
only one single shared memory region to split amongs all the allocated
instances. When the platform has more than one core this is obviously
not the case since each couple of cores are communicating using a
different memory region.
To solve this issue we introduce a new struct rpmsg_mi_ctx_shm_cfg that
is doing two things: (1) it's carrying the information about the shared
memory and (2) it's carrying an internal variable used to track the
instances allocated in that region. The same struct should be used every
time a new instance is allocated in the same shared memory region.
We also fix a problem with the current code where there is a race
between threads when accessing the instance variable, so this patch is
adding a serializing mutex.

For the instance configuration the rpmsg_multi_instance code is
currently using a set of configuration info coming from two different
sources: the rpsmg_mi_ctx_cfg struct and Kconfig.
This is not only confusing but it's preventing to configure the
instances using information not coming from Kconfig (for example if we
want to configure the instance using DT).
