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

Fix missing transmit buffer demutiplexing before checking if

Update LLCP handling during PHY update and Data Length update to not
start the LL control procedure if the remote has already indicated that
the procedure is not supported.
This fulfills the following requirement from the BT Core Specification
(Core_v5.2, Vol 6, Part B, Section 4.6):
Except where explicitly stated elsewhere in this specification, if the
peer Link Layer has indicated either during a feature exchange procedure
or by responding with an LL_UNKNOWN_RSP PDU that it does not support a
procedure, then the Link Layer shall not use that procedure.
Re-use the connection parameter request handling for PHY and
data length update procedures.

Data transmission was paused when PHY update request control
PDU was enqueued in ULL. If there was pending data PDU in
ULL that was not enqueued towards LLL, this caused
transmission to stall.
Move the tx pause due to PHY update request/response being
enqueued to pre_tx_ack callback, this way all pending PDUs
in ULL is enqueued to LLL.

If LL Connection Parameter Request or LL Connection Update
or LL PHY Update procedure is started by the local device
while a LL Length Update Request PDU has been sent by peer
then a Rx node has been stored in the llcp_rx place holder
for generation of Length Update procedure complete.
The failing assert check is incorrect in the above scenario
hence remove. Instead a missing append of the allocated Rx
node to the llcp_rx list has been added to the controller
implementation.
