Port all users of 'set_conf_file' to use the built-in rules

In-tree, all usage of 'set_conf_file' is implementing the same
pattern (with some inconsequential differences).
To reduce copy-paste and get closer to dropping support for
'set_conf_file', we include this pattern into the built-in set of
patterns.
'set_conf_file' is causing issues for future extensions,
e.g. multi-image support, and is also the source of a lot of
duplicated code.
Note support for 'set_conf_file' is not dropped, it is only marked as
deprecated.

Zephyr Continuous Integration made the choice of rebasing pull requests
on its fast moving master branch before testing them. Unfortunately the
Shippable interface assumes the other choice[*] and highlights the SHA1
of the pull request _before_ rebasing which is very misleading. For now
the only way to realize this disconnect is to scrutinize the build logs
and/or this source code (or tribal knowledge).
To mitigate and reduce a bit this confusion, run a short:
git log -n 5 --oneline --decorate
before and after rebase.
Making it worse, Shippable sub-runs are not pegged to a common base
version. For instance the reason why shippable sub-run 35578.1 passed
while all other 35578.x sub runs failed is very likely because PR #13803
was merged to master in the mean time. This commit would have been able
to prove that.
[*] In an ideal world with infinite time and resources, Continuous
Integration would test pull requests BOTH alone and combined with the
moving tip.

The newer series of timer drivers will compare counters vs. the last
tick boundary to compute a number of ticks to announce to the kernel.
In the case of CONFIG_TICKLESS=n, this actually represents a change of
behavior from our old scheme where "ticks" always reflected the number
of interrupts received.
The distinction only matters when an interrupt is delayed more than a
full tick, of course. But that actually makes a difference to some
timekeeping code. Restore the old behavior.
This also has the benefit of further reducing code size when !TICKLESS
and improving performance of the ISR by removing the division
(remember Cortex M0 has no hardware divide!).

Zephyr has always been a uniprocessor system, and its kernel tests are
rife with assumptions and outright dependence on single-CPU operation
(for example: "low priority threads will never run until this high
priority thread blocks" -- not true if there's another processor to
run it!)
About 1/3 of our tests fail right now on x86_64 when dual processor
operation is made default. Most of those can probably be recovered on
a case-by-case basis with simple changes (and a few of them might
represent real bugs in SMP!), but for now let's make sure the full
test suite passes by turning the second CPU off. There's still plenty
of SMP coverage in the remaining cases.

This commit reworks the logic, based on which we assess
thread stack corruptions upon BusFault exceptions triggered
by the NXP MPU module. BusFaults rely on calling external
function to assess whether a thread stack corruption due to
overflow has occurred. Upon detection of stack corruption,
the current stack pointer is manually adjusted upwards, to
prevent un-stacking errors from firing up upon returning from
the exception.
Additionally, the commit allows to be checking for all different
types of BusFault occurrences that are reported through BFSR,
without stopping after having spotted the first BusFault type.

driver to report tick changes) was needed for correct operation on
nRF52.

MISRA rules (see #11425) forbid recursive algorithms. In the case of
rb_walk(), it's not actually used anywhere but a test right now, so we
can simply disable the API when CONFIG_MISRA_SANE is defined. Mempool
had a (IMHO, fairly clever) tail recursive loop in bfree_recombine()
which can be trivially transformed into an only slightly uglier
iterative version.

MISRA rules (see #9892) forbid alloca() and family, even though those
features can be valuable performance and memory size optimizations
useful to Zephyr.
Introduce a MISRA_SANE kconfig, which when true enables a gcc error
condition whenever a variable length array is used.
When enabled, the mempool code will use a theoretical-maximum array
size on the stack instead of one tailored to the current pool
configuration.
The rbtree code will do similarly, but because the theoretical maximum
is quite a bit larger (236 bytes on 32 bit platforms) the array is
placed into struct rbtree instead so it can live in static data (and
also so I don't have to go and retune all the test stack sizes!).
Current code only uses at most two of these (one in the scheduler when
SCHED_SCALABLE is selected, and one for dynamic kernel objects when
USERSPACE and DYNAMIC_OBJECTS are set).
This tunable is false by default, but is selected in a single test (a
subcase of tests/kernel/common) for coverage. Note that the I2C and
SPI subsystems contain uncorrected VLAs, so a few platforms need to be
blacklisted with a filter.
