Previously the host would handle disconnecting associated CISes and
invoking callbacks when a host ACL conn was disconnected.
This responsibility has now been moved to the controller, which needs to
send a NODE_RX_TYPE_TERMINATE with the CIS handle for proper
disconnection in the host. This is in accordance with the spec.
As disconnect reason, the CIS uses the ACL reason, which is passed to
the host along with the handle.

First implementation of periodic advertising sync filtering
requires existence of Direction Finding Extension in Radio
peripheral.

Follow up on changes in lower link layer to add filtering
of periodic advertisements synchronization by CTE type.
The NODE_RX_TYPE_SYNC is used to transport information that:
- Sync is established. In such situation the node_rx
includes data related with received PDU
- Sync scanning is terminated.
In first case ULL will generate NODE_RX_TYPE_SYNC_REPORT
after sending NODE_RX_TYPE_SYNC.
Also EVENT_DONE_EXTRA_TYPE_SYNC handling has additional
execution path that terminates sync scanning if requested
by lower link layer. In other case it adjusts sync scan
window and maintains timeout as usual.

Periodic advertisement synchronization may be filtered by CTE type.
If particular CTE type is not allowed then depening on filtering policy:
- if filtering policy is off synchronization if terminated
- if filtering policy is on synchronization is continued to
synchonize with another device from allowed adverisements list.
If synchronization is established and peer device changes CTE type
to one that is not allowed, synchronization should be maintained.
There are two new execution paths. First one is executed when
synchronization is created. In this case CTEILINE is enabled
to parse PDU for CTEInfo field. In this execution path CTE
type is verified. Second execution path does not include
parsing PDU for CTEInfo and verification of CTE type.
Information about sync allowed is added to node_rx instance
that transports received PDU data. In case the sync has to be
terminated the node_rx will not hold PDU data.
Also done event is extended with information about sync
termination if CTE type is not allowed and filtering
policy is off.

To enable runtime parsing of PDU to find CTEInfo field CTEINLINE mode
has to be enabled. Thanks to that it is possible to verify if the PDU
has allowed CTE type e.g. for periodic advertising synchornization.
To run CTEInfo parsing other parametrers of CTEINLINE are not relevant.
If Radio is set to disable after PDU END event the CTE sampling
will not be processed.
The commit moves the radio_df_cte_inline_set_enable function to make
it accessible even the direction finding features are disabled.

When there are radio events with time reservations lower
than the preemption timeout of 1.5 ms, the pipeline has to
account for the maximum radio events that can be enqueued
during the preempt timeout duration. All these enqueued
events could be aborted in case of late scheduling needing
as many done event buffers.
During continuous scanning, there can be 1 active radio
event, 1 scan resume and 1 new scan prepare. If there are
peripheral prepares in addition, and due to late scheduling
all these will abort needing 4 done buffers.
If Extended Scanning is supported, then an additional
auxiliary scan event's prepare could be enqueued in the
pipeline during the preemption duration.
