Until now iterable sections APIs have been part of the toolchain
(common) headers. They are not strictly related to a toolchain, they
just rely on linker providing support for sections. Most files relied on
indirect includes to access the API, now, it is included as needed.

It is frequent to find variable definitions like this:
```c
static const struct device *dev = DEVICE_DT_GET(...)
```
That is, module level variables that are statically initialized with a
device reference. Such value is, in most cases, never changed meaning
the variable can also be declared as const (immutable). This patch
constifies all such cases.

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

Improve code by using DEVICE_DT_GET_ONE instead of device_get_binding,
since the intel_vt_d device instance can be obtained at compile time.

Allocate an IRTE for all irq being connected through
arch_irq_connect_dynamic(). This will be mandatory since VT-D expects to
filter all interruptions (but the one it generates, as we will see
later).
Taking into account CONFIG_INTEL_VTD_ICTL_XAPIC_PASSTHROUGH, which could
help for debugging.

This will be used by MSI multi-vector implementation to connect the irq
and the vector prior to allocation.

Most of kernel files where declaring os module without providing
log level. Because of that default log level was used instead of
CONFIG_KERNEL_LOG_LEVEL.

This will be needed when we support memory un-mapping, or
the same user mode page tables on multiple CPUs. Neither
are implemented yet.

Right now x86_64 doesn't install handlers for vectors that aren't
populated by Zephyr code. Add a tiny spurious interrupt handler that
logs the error and triggers a fatal error, like other platforms do.

We use a fixed value of 32 as the way interrupts/exceptions
are setup in x86_64's locore.S do not lend themselves to
Kconfig configuration of the vector to use.
HW-based kernel oops is now permanently on, there's no reason
to make it optional that I can see.
Default vectors for IPI and irq offload adjusted to not
collide.

Promote the private z_arch_* namespace, which specifies
the interface between the core kernel and the
architecture code, to a new top-level namespace named
arch_*.
This allows our documentation generation to create
online documentation for this set of interfaces,
and this set of interfaces is worth treating in a
more formal way anyway.

Duplicate definitions elsewhere have been removed.
A couple functions which are defined by the arch interface
to be non-inline, but were implemented inline by native_posix
and intel64, have been moved to non-inline.
Some missing conditional compilation for z_arch_irq_offload()
has been fixed, as this is an optional feature.
Some massaging of native_posix headers to get everything
in the right scope.

This is the Wrong Thing(tm) with SMP enabled. Previously this
worked because interrupts would be re-enabled in the interrupt
entry sequence, but this is no longer the case.

This makes it clearer that this is an API that is expected
to be implemented at the architecture level.

This is largely a conceptual change rather than an actual change.
Instead of using an array of interrupt stacks (one for each IRQ
nesting level), we use one interrupt stack and subdivide it. The
effect is the same, but this is more in line with the Zephyr model
of one ISR stack per CPU (as reflected in init.c).

Fleshed out z_arch_esf_t and added code to build this frame when
exceptions occur. Created a separate small stack for exceptions and
shifted the initialization code to use this instead of the IRQ stack.
Moved IRQ stack(s) to irq.c.
