Don't attempt to take a mutex if operating from inside an ISR. The only
expected use-case where this should occur is when attempting to reboot
via `tfm_platform_system_reset` from an exception handler.

This commit follows the parent commit work.
This commit introduces the following major changes.
1. Move all directories and files in 'include/zephyr/arch/arm/aarch32'
to the 'include/zephyr/arch/arm' directory.
2. Change the path string which is influenced by the changement 1.

The CMSIS module glue code was part of arch/ directory. Move it to
modules/cmsis, and provide a single entry point for it: cmsis_core.h.
This entry header will include the right CMSIS header (M or A/R).
To make this change possible, CMSIS module Kconfig/CMake are declared as
external, allowing us to add a new Zephyr include directory.
All files including CMSIS have been updated.

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

Fixes an issue where thread preemption was not being disabled
correctly, failing to taking into account MetaIRQ, which can be
used to preempt any cooperative thread.
The updated code sets the current thread to `K_HIGHEST_THREAD_PRIO`
before calling the secure function, and restores the thread priority
level once secure execution has terminated, allowing the thread
to be preempted once again.

When ARM_NONSECURE_PREEMPTIBLE_SECURE_CALLS is enabled, if FPU is
being used (CONTROL.FPCA == 1), store all FP registers before
entering the secure function, and restore them afterwards.
This is needed if any NS thread or ISR that interrupts the secure
function uses FP registers. If they do, a secure UsageFault occurs
unless this change is applied.
This allows k_sched_lock() and k_sched_unlock() to be dropped when
ARM_NONSECURE_PREEMPTIBLE_SECURE_CALLS is enabled.
Enable ARM_NONSECURE_PREEMPTIBLE_SECURE_CALLS by default when
building TF-M.

we can use TF-M interface calls (veneers).
