- No more need for special IRQ shadow stacks - just reuse the one
created for z_interrupt_stacks;
- Add the linker sections for the pairs of stack/shadow stack;
- Support shadow stack arrays.
Last item was a bit challenging: shadow stacks need to be initialised
before use, and this is done statically for normal shadow stacks. To
initialise the shadow stacks in the array, one needs how many entries it
has. While a simple approach would use `LISTIFY` to them do the
initialization on all entries, that is not possible as many stack arrays
are created using expressions instead of literals, such as
`CONFIG_MP_MAX_NUM_CPUS - 1`, which won't work with `LISTIFY`.
Instead, this patch uses a script, `gen_static_shstk_array.py` that
gathers all needed information and patches the ELF to initialize the
stack arrays. Note that this needs to be done before any other operation
on the ELF file that creates new representations, such as the .bin
output.

So that kernel created threads can use shadow stacks. Note that
CONFIG_X86_CET_SHADOW_STACK is abandoned in favour of
CONFIG_HW_SHADOW_STACK.
This means change some types, functions and macro throughout shadow
stack code.

This commit inlines the direct ISR functions that were previously
implemented in irq_manage.c, since the PR #20119 resolved the circular
dependency between arch.h and kernel_structs.h described in the issue
#3056.

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.

include/sys/arch_inlines.h will contain all architecture APIs
that are used by public inline functions and macros,
with implementations deriving from include/arch/cpu.h.
kernel/include/arch_interface.h will contain everything
else, with implementations deriving from
arch/*/include/kernel_arch_func.h.
Instances of duplicate documentation for these APIs have been
removed; implementation details have been left in place.

Various C and Assembly modules
make function calls to z_sys_trace_*. These merely call
corresponding functions sys_trace_*. This commit
is to simplify these by making direct function calls
to the sys_trace_* functions from these modules.
Subsequently, the z_sys_trace_* functions are removed.
