Fix missing ISO Synchronized Receiver radio event time
reservation that did not calculate for all the subevents.
Introduce BT_CTLR_SYNC_ISO_RESERVE_MAX Kconfig option to
allow using a minimal time reservation if needed to allow
other role to pre-empt ISO Synchronized Receiver in
pre-transmission and control subevents.

If runtime_suspend() is called early during Zephyr initialisation,
while k_is_pre_kernel() returns 'true,' 'async' is set to 'false,' so
if 'async' is 'true,' Zephyr initialisation is definitely complete,
so there is no need to check k_is_pre_kernel() again.

The HDA log backend has been buggy for some time, and the fixes are well
understood. The issue with HDA log as it is implemented today means
there are concurrency and ISR issues where it can deadlock.
The fixes are effectively dropping the usage of ipc to communicate
status, using polling on the hda stream, and having a formatter per call
context (cores + isr) when log mode immediate is enabled to fix log
mangling. However it was found this had a lot of unintentional side
effects that made it difficult to make progress on when it came to
changes of the host side python tooling.
Meanwhile the feature has sat unused for nearly a year. Remove it, and
it can always be revisited in the future if something like it happens to
be needed.

Previously it was not always possible to prepend the header.
It was not possible if the application neglected to reserve the space
for headers. This is bad because it forces a buffer segment allocation
even if the buffer had enough room for the headers. E.g. a payload of 10
bytes in a netbuf of 30 bytes would have been segmented.
We now explicitly reject the buffer if it does not have the headroom.
This allows us to do a nice thing; simplify L2CAP segmentation.
We convert the SDU from the application into a PDU payload, by
prepending the SDU header, i.e. the SDU length in the original buffer.
This PDU payload is ready to be chunked into PDUs without having to keep
track of where in the SDU we are. This has the effect of removing a
bunch of logic in the segmentation machine.

Some of the ASCS response codes should not be used by the
unicast server, as those will be checked and validated by the
stack.
They are kept in the enum, as the enum is also used by the
unicast client.
Besides updating the documentation, this commit also adds
a function to validate the response codes as well as the
combination of response codes and reason/metadata values,
and log a warning if the application does not adhere to the
documented behavior.
A warning is used instead of an error/assert/modification
of the response codes, as there may be unforseen reasons
why an application provide a non-approved response code,
and since it may be spec-valid, we should not fully
prevent it.

This PR makes the modem_chat wait until a chat script chat
request has been sent before accepting responses to said
request.
This helps ensure that an unsolicitet response is not mistaken
for a response to a request, which is especially problematic
if the chat script chat is using an any match.
For example, start chat script sending AT+CGMI, expecting the
modem name as a response followed by OK
> start script, waiting for response immediately
> start sending "AT+CGMI"
> receive "+CEREG 1,0" while sending
> script accepts "+CEREG 1,0" as the response to "AT+CGMI"
> "AT+CGMI" sent
> receive "QUECTEL BG95"
> receive "OK"
script handler got "+CEREG 1,0" instead of "QUECTEL BG95"
After this PR:
> start script
> start sending AT+CGMI
> receive "+CEREG 1,0" while sending
> "AT+CGMI" sent
> start waiting for response
> receive "QUECTEL BG95"
> script accepts "QUECTEL BG95" as response to "AT+CGMI"

this function. We can therefore remove the line adding a null terminator

Fix ull_prepare_dequeue to not skip events when preempt
does not match the event in the head of the prepare queue.
The head of the prepare queue does not match when
ull_prepare_dequeue has put the head of the queue to the
last of the queue when it is calling lll_resume interface.
This happens when there is already an active event which
needs a preempt timeout to be setup and there is another
non-resume event in the pipeline which now becomes the
head. The fix ensure to restore the order of the events
if a preempt timeout was to be setup.
Currently ull_prepare_dequeue loops through all events
before stopping at the original way the queue was. This is
not efficient and is a scope for improvement in future.
This reverts commit 91781306e9 ("Revert "Bluetooth:
Controller: Fix ull_prepare_dequeue for skipped events"").
