This commit introduces the ARMV8_M_SE K-config option
to signify the use of an ARMv8-M MCU with support for
Security Extensions. It also introduces dependences of
ARM_(NON)SECURE_FIRMWARE on ARMV8_M_SE.

12f8f7616 but it is not used by the build system. CMakeLists.txt in
the parent dir lib/libc/minimal/CMakeLists.txt adds C files to the
target with the lines like:
${CMAKE_CURRENT_SOURCE_DIR}/source/stdlib/atoi.c
${CMAKE_CURRENT_SOURCE_DIR}/source/stdlib/strtol.c
To make other empty CMakeLists.txt explicit, this commit adds a

On Cortex-M7 CPU (at least on STM32F723), the dummy move FPU instruction
is executed before the FPU lazy state preservation is disabled. Add an
instruction synchronization barrier before it to avoid that.
At the same time, remove the data synchronization barrier after the
dummy move as it does not have any effect on RAM or registers.

This commit removes the arm_mpu_enabled status flag in the ARM
MPU driver. This flag is not needed, because the value of the
MPU_CTRL register stays the same while the MPU is enabled, and
is cleared to 0 when the MPU is disabled. Therefore, we do not
need to prevent from having the enable or the disable operation
to be called multiple times.

ARM Cortex-M0+, M3, and M4 MCUs have a fixed number of 8 MPU
regions, if MPU support is implemented. Therefore, we can
implement _get_num_regions() to return a constant, if CPU
is one of the above Cortex variants. _get_num_regions() is
invoked often in the code, so this solution increases processing
efficiency. A sanity check is implemented in arm_mpu_init(), to
ASSERT if the number of regions provided by hardware does not
match the expected (default) value.

The original implementation of CONFIG_THREAD_MONITOR would
try to leverage a thread's initial stack layout to provide
the entry function with arguments for any given thread.
This is problematic:
- Some arches do not have a initial stack layout suitable for
this
- Some arches never enabled this at all (riscv32, nios2)
- Some arches did not enable this properly
- Dropping to user mode would erase or provide incorrect
information.
Just spend a few extra bytes to store this stuff directly
in the k_thread struct and get rid of all the arch-specific
code for this.

BUILD_OUTPUT_HEX was enabled by default for stm32 SoCs.

On ARM, the __thread_entry struct pointer used when
CONFIG_THREAD_MONITOR is enabled was pointing to the initial exception
stack frame. That's not right: even though this contains all the same
info, it's not layout-compatible with the API struct. And once the
thread starts running, the ESF gets unwound and the memory recliamed
for the stack frame of the entry function!
Stuff the __thread_entry struct into its own memory at the bottom of
the stack like the other architectures do. Fixes#7541
