22f73992b2 Bluetooth: Rework the HCI header set
In order to have clean, self-contained HCI headers that do not have any
dependencies towards the Host or any other part of the system (except
types), reorganize the headers in the following way:

- Split out the macros and structs from hci.h to a new hci_types.h
- Merge the existing hci_err.h into the new hci_types.h

Fixes #58214.

ff89e98cc6 Bluetooth: controller: Release missing / lost SDUs for framed PDUs
-- Implemented reporting of lost / missing SDUs for framed PDUs. This
   should result in SDUs being released when only framed padding PDUs or
   error PDUs are received.
-- Removed unused configuration params structure, storage and linked
   APIs.
-- Reduced default logging level to INF instead of DBG.
-- Included debug logging messaged for framed consumption.
-- Removed separate latency_unframed and latency_framed and replaced
   with a common sdu_sync_const as they are mutually exclusive for each
   sink.
-- Restricted framed time stamp calculation only to situations where all
   dependent information is available.
-- Corrected SDU sequence numbering to release starting at zero.

0398d8ddf6 Bluetooth: controller: Release SDU as missing if RX only unf. padding
Based on interpretation of Clarification Errata ES-22876 Request for
Clarification - Recombination actions when only padding unframed PDUs
are received, it was decided that an SDU should be released as "Missing"
when only padding PDUs are received for any SDU.
- https://bluetooth.atlassian.net/browse/ES-22876

This change will also assist streaming in the Common Central design
where the central was found to send only padding PDUs before streaming

On CIS disconnect, the peripheral will clear all data paths.

However ll_remove_iso_path will fail if attempting to remove a

function returned an error and never attempted to clear the other

5db51d3679 Bluetooth: controller: Fix reconfiguring of CIG and CISes
Up until now, it has not been possible to reconfigure a CIG and its
CISes after initial configuration, without first removing the CIG.

With this commit, le_set_cig_parameters allows the following
reconfiguration operations in configuration state:
- Set new CIG configuration parameters on existing CIG
- Iteratively configure single CIS (of more CISes)
- Increment number of CISes via multiple configuration calls
- Keep handle- and CIS_ID relation

Changes:
- Pass handles in le_set_cig_parameters from ll_cig_parameters_commit
  via output variable.
- Implement CIG state variable instead of 'started', with states
  IDLE/CONFIGURABLE, ACTIVE and INACTIVE.
- Implement ll_conn_iso_stream_get_by_id for easier access to specific
  CIS.

This fixes the following CIS Central EBQ tests:
- HCI/CIS/BI-10-C
- HCI/CIS/BI-11-C
- HCI/CIS/BI-13-C
- HCI/CIS/BV-05-C

622299b1c5 Bluetooth: controller: Move DF feat selection to LL_SW_SPLIT KConfig
The BT_CTLR_DF_SUPPORTED KConfig was a wrapper for DF related features
set that are supported by Zephyr's BLE Controller. At the same time the
KConfig is used by Host in compound build to enable BT_DF. That makes
the whole thing a bit coupled with Zephyr's controller.
External implementations of controller must provide same feature set
as Zephyr's Controller or there will be an error during build.

The PR moves the Zephyr's Controller DF supported features set to
Kconfig.ll_sw_split, where it is included only when BT_LL_SW_SPLIT
is selected. BT_CTLR_DF_SUPPORTED is now a top DF_SUPPORTED KConfig
option that enables possibility to select actual DF features.
That allows to select individual set of DF features by any controller
implementation and makes possible to enable BT_DF and build selected
DF Host features.

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.
