Derive BT_CTLR_ISO_TX_BUFFER_SIZE from BT_ISO_TX_MTU to have
optimal Controller memory allocations.
BT_CTLR_ISO_TX_BUFFER_SIZE can be set lower than
BT_ISO_TX_MTU in which case upper layer can send fragmented
SDU to the Controller.

Redefine mask of host-controlled feature bits to include only features
that are supported by the controller. This fixes a conformance test
failure where setting an unsupported host-controlled feature bit was
not rejected as it should.
Set the Connected Isochronous Streams (Host Support) bit from the host
only if unicast support is configured to avoid failures in
broadcast-only configurations.

Fix BT_CTLR_ADV_DATA_LEN_MAX and other Kconfig dependencies,
and clean up the use of PDU_AC_LL_SIZE_MAX which is used to
allocate scratch packet to be atleast able to accommodate
the minimum 31 bytes AD data such that it is sufficient to
transmit and/or receive scan response PDUs when either
broadcaster or observer alone is supported.

In a Host plus Controller combined build for ISO feature
restrict the maximum ISO Tx PDU size to minimum of 251 bytes
and Host ISO Tx MTU. This will allow controller to use
reduced Tx time (subevent interval).

Pushes all work done in the topic-ble-llcp branch into main branch
This is a refactoring of the LL control procedures; the refactored
control procedures are hidden behind a KConfig option and
per default disabled
Goal of the refactoring:
close issue Link Layer Control Procedure overhaul #15256
make it easier to add/update control procedures
Refactoring consists in principal of writing explicit state machines
for the control procedures.
To reduce the risk of regression errors unit-tests have been added
Following control procedures are implemented:
Connection update procedure
Channel map update procedure
Encryption procedure
Feature exchange procedure
Version exchange procedure
ACL termination procedure
Connection parameters request procedure
LE Ping procedure
Data Length Update procedure
PHY update procedure
Min. nr. Of channels used procedure
Constant Tone extension request procedure
This is a joined work by the people listed in the signed-off-by
list (in alphabetical order)

The existing feature exchange procedure does not give the proper
response as specified in the BT core spec 5.0.
The old behaviour is that the feature-response returns the logical and
of the features for both peers.
The behaviour implemented here is that the feature-response returns the
featureset of the peer, except for octet 0 which is the logical and of
the supported features.
Tested by using the bt shell, and having different featuresets
on the 2 peers.
This fixes#25483

SMI TX is different than other controller features in that it does not
necessarily imply any software changes; whether SMI TX is supported
may be simply a matter of hardware calibration. This change supports
using the same software on chips that do or do not support SMI TX
depending on calibration.

Preparation to introduce the Upper Link Layer (ULL) and
Lower Link Layer (LLL) split architecture.
- Move SoC dependent HAL to vendor specific folder.
- Preparation to split data structures into ULL and LLL
types.
- Added more role and state conditional compilations.
- Added some work-in-progress implementation of advertising
extensions, will be used as inspiration in the new split
architecture work.
