Out-of-tree code can still be using the old file locations. Introduce
header shims to include the headers from the new correct location and
print a warning message.
Add also a new Kconfig symbol to suppress such warning.
The shim will go away after two releases, so make sure to adapt your
application for the new locations.

Before introducing the code for ARM64 (AArch64) we need to relocate the
current ARM code to a new AArch32 sub-directory. For now we can assume
that no code is shared between ARM and ARM64.
There are no functional changes. The code is moved to the new location
and the file paths are fixed to reflect this change.

Consistently place C++ use of extern "C" after all include directives,
within the negative branch of _ASMLANGUAGE if used.
In arch.h the extern "C" in the including context is left active during
include of target-specific mpu headers to avoid more complex
restructuring.
Background from issue #17997:
Declarations that use C linkage should be placed within extern "C"
so the language linkage is correct when the header is included by
a C++ compiler.
Similarly #include directives should be outside the extern "C" to
ensure the language-specific default linkage is applied to any
declarations provided by the included header.

These changes were obtained by running a script created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:
1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
#define X Y)
3. Check if that name is also the name of a Kconfig option
3.a If it is, then do nothing
3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
(.c, .h, .ld)
Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.
Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

This commit removes the macros for ARM fault flags from
include/arch/arm/cortex_m/cmsis.h header, since they are
defined in the respective core_cmXX.h header files. It also
modifies fault.c to use the updated fault macros taken directly
from ARM CMSIS headers.

This PR includes the required changes in order to support
conditional compilation for Armv8-M architecture. Two

- the Armv8-M Mainline (backwards compatible with ARMv7-M).

We need to make sure that __NVIC_PRIO_BITS & CONFIG_NUM_IRQ_PRIO_BITS
are set to the same value. Add a simple build time check to ensure
this is the case. This is to catch future cases of issues like
ZEP-2243. This is a stop gap til we resolve ZEP-2262, which covers use
of both __NVIC_PRIO_BITS & CONFIG_NUM_IRQ_PRIO_BITS.

Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types. This handles the remaining includes and kernel, plus
touching up various points that we skipped because of include
dependancies. We also convert the PRI printf formatters in the arch
code over to normal formatters.

Support using CMSIS defines and functions, we either pull the expect

provide a default set based on __NVIC_PRIO_BITS is defined.
We provide defaults in the case for:
IRQn_Type enum
*_REV define (set to 0)
__MPU_PRESENT define (set to 0 - no MPU)
__NVIC_PRIO_BITS define (set to CONFIG_NUM_IRQ_PRIO_BITS)
__Vendor_SysTickConfig (set to 0 - standard SysTick)
