In order to bring consistency in-tree, migrate all subsystems code to
the new prefix <zephyr/...>. Note that the conversion has been scripted,
refer to zephyrproject-rtos#45388 for more details.

The new JIT scheduler does not have slot reservation, which means that
the ticker extension feature for automatically re-scheduling a colliding
non-anchored event, e.g. ADV, cannot be used.
This implementaion reacts to ADV envent done with result ABORTED or
TOO_LATE, and in those cases attempts to re-schedule the ADV event again
within the 10 ms pertubation window.
As the original scheduling, the re-scheduling is randomized, so there
is no absolute predictability as to how many attempts will be made. The
advertiser will attempt with randomly delayed re-schdules until the
window is exhausted.
If re-scheduling is unsuccessful, the weight of the ADV event is
increased, improving it's chances of success in the next event.

This option enables BT_TICKER_SLOT_AGNOSTIC which eliminates
priorities and collision resolving in the ticker.
Event scheduling states are stored in the lll_hdr, and event priority
is passed from LLL implementation, and runtime priority calculated.
LLL implementation decides whether to program radio, start preemption
timer, and/or queue prepare in the prepare pipeline.
Event arbitration is made possible via the common LLL, but not yet
implemented in Nordic LLL.

Split lll_prepare and lll_resume from Nordic LLL to common file for
reuse by all vendors. The split also supports new JIT Scheduling by
defining a common place to calculate event prepare priority.
The module may also house other common parts of the LLL currently
re-implemented identically by vendors.
