The #if to use static_assert() for BUILD_ASSERT() only checks
whether compiler is in C++ mode, but does not check what
C++ standard is being used. Since static_assert() is only
valid since C++11, for compilers not supporting C++11 (XCC...),
this will result in error. So add the correct #if to also
check for C++ standard being used.

BUILD_ASSERT macro was disabled for MWDT toolchain from the
moment of adding MWDT support to Zephyr. Built-in _Static_assert
is now working fine for the most of the cases with MWDT toolchain
so we can use it in BUILD_ASSERT.
The only exception is _ARCH_MEM_PARTITION_ALIGN_CHECK macro
as it often used with variable addresses as parameters
which need to be checked at compile time. We disable
_ARCH_MEM_PARTITION_ALIGN_CHECK for MWDT toolchain so we can use
BUILD_ASSERT in other places.

The generic version of SECTION_VAR() is adding an extra space

- AArch64 boards and SoC are moved to soc/arm64 and boards/arm64

This adds a new GEN_ABSOLUTE_SYM_KCONFIG() specifically for
generating absolute symbols in assembly for kconfig values.
This is needed as the existing GEN_ABSOLUTE_SYM() with
constraints in extended assembly parses the "value" as
signed 32-bit integers. An unsigned 32-bit integer with
MSB set results in a negative number in the final binary.
This also prevents integers larger than 32-bit. So this
new macro simply puts the value inline within the assembly
instrcution instead of having it as parameter.

Make the assembly codes compatible with both GNU
and Metaware toolchain.
* replace ".balign" with ".align"
".align" assembler directive is supposed by all
ARC toolchains and it is implemented in a same
way across ARC toolchains.
* replace "mov_s __certain_reg" with "mov __certain_reg"
Even though GCC encodes those mnemonics and even real
HW executes them according to PRM these are restricted
ones for mov_s and CCAC rightfully refuses to accept
such mnemonics. So for compatibility and clarity sake
we switch to 32-bit mov instruction which allows use
of all those instructions.
* Add "%%" prefix while accessing registers from inline
ASM as it is required by MWDT.
* Drop "@" prefix while accessing symbols (defined in C
code) from ASM code as it is required by MWDT.

For iterable areas defined with Z_STRUCT_SECTION_ITERABLE(),
the corresponding output section in the linker script is just
boilerplate. Add macros to make these definitions simpler.
Unfortunately, we have a fair number of iterable sections not
defined with Z_STRUCT_SECTION_ITERABLE(), this patch does not
address this.
The output sections are all named <struct name>_area, update
sanitylib.py with this.
sys_sem with no userspace, and k_lifo/k_fifo are special cases
where different data types that are all equivalent need to be
put in the same iterable area. Add
Z_STRUCT_SECTION_ITERABLE_ALTERNATE() for this special case.
