Fix the calculation of event delay when starting a radio
event. The calculation and check was incorrect causing
event abort when radio event was setup before the preempt
timeout by the lll_done when the next prepare was already
in the pipeline.

When a CIS indication is received and CIG ticker is already started,
calculate the absolute time of the first subevent of the new CIS,
and validate the handle. This will allow the LLL prepare to see a new
valid CIS, and calculate the offset within the CIG event, where the new
CIS should start. This offset is then valid for all following events for
the duration of the CIS.

Fix control Tx buffer leak into data Tx pool that happens
after a cross-over control procedure response was paused due
to currently active encryption setup procedure, and a new
control Tx PDU in addition to the paused one is enqueued
thereafter.
When the control tx PDUs is resumed but not yet enqueued
towards the radio, if there is a new control Tx PDU enqueued
then the paused control Tx PDU is not set as the head of the
control PDUs in the Tx queue. This caused the paused control
Tx PDU to be associated with data Tx pool, hence causing the
incorrect release into data Tx pool.
Relates to the commit bff76b4cce ("Bluetooth: controller:
split: Fix control tx queue handling") and to the
commit 6991d09977 ("Bluetooth: controller: Fix control tx
queue handling").

Currently there is no way to distinguish between a caller
explicitly asking for a semaphore with a limit that
happens to be `UINT_MAX` and a semaphore that just
has a limit "as large as possible".
Add `K_SEM_MAX_LIMIT`, currently defined to `UINT_MAX`, and akin
to `K_FOREVER` versus just passing some very large wait time.
In addition, the `k_sem_*` APIs were type-confused, where
the internal data structure was `uint32_t`, but the APIs took
and returned `unsigned int`. This changes the underlying data
structure to also use `unsigned int`, as changing the APIs
would be a (potentially) breaking change.
These changes are backwards-compatible, but it is strongly suggested
to take a quick scan for `k_sem_init` and `K_SEM_DEFINE` calls with
`UINT_MAX` (or `UINT32_MAX`) and replace them with `K_SEM_MAX_LIMIT`
where appropriate.
