Use accumulated connected ISO LLL prepare callback latencies
to check supervision timeout.
Also use the accumulated connected ISO LLL prepare callback
latencies to adjust SN and NESN values.
Connection establishment can cause short prepare callbacks
inserted before Connected ISO group prepare callbacks, that
cause the Connected ISO group prepare callbacks being
cancelled while being in prepare pipeline. Hence, it is
necessary to accumulate prepare callback latencies wherein
ticker callbacks are executed but prepare callbacks are
cancelled in the prepare pipeline.

Implementation of preliminary Central with multiple CIS
create support in Lower Link Layer. Uses a simple CIS
offset calculation that works when ACL are created with
connection interval that is multiple of CIG ISO interval.
Each ACLs are offset using BT_CTLR_CENTRAL_SPACING hence
having the same CIG sync delay values for all the ACLs.
Advanced Scheduling to setup CIS in any order of ACL and
CIS combination, ACL placed anywhere in timeline and CIS
creation will come therein will be implemented in later
Pull Requests.

-- ISO-AL microsecond time wrapping exposed to be used externally to
adjust incoming Group Reference Points and Time-stamps where required
-- Function that handles adjustment of payload number according to
incoming SDU exposed for external use to allow next payload number to
be accessed by ISO transmit tests

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

Update ticker implementation to reschedule unreserved ticker
that use ticks_slot_window.
This will avoid unreserved ticker from continuously
overlapping with reserved tickers. And the change is
required to reduce processing overheads before reserve
ticker timeout callback executes.
Unreserved tickers with ticks_slot_window will always yield
to any colliding reserved or unreserved tickers.
The implementation moves unreserved tickers (no ticks_slot
value, in this case continuous scan window) to end of a
colliding reserved/unreserved ticker so that reserved
tickers (like central role) do not have high overheads due
to unreserved ticker's prepare (scanner) be preempted
everytime before reserved ticker's prepare (central).

In general, RTC and TIMER driver implements counter API but there
are exception when those peripherals are used in a custom way
(e.g. for system timer or bluetooth). In that case, system must
prevent using counter based on a reserved instance. Previously,
it was managed by Kconfig options but that cannot be maintained
when switching to devicetree configuration of the counter driver.
A new approach removes Kconfig options and instead adds static
asserts in the files which are using direct peripherals. Those
asserts check if given node is not enabled in the device tree.

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.
