Currently we try to manually specify C/C++ headers locations
with -isystem flag which lead to issues with "include_next"
directive which is used in C/C++ headers. As advised by MWDT
R&D team let's rely on the default C/C++ include locations
which are provided by MWDT if we do build with MW C / C++
libraries. For that case we still need to manually specify
header directory to ASM builds which bay use 'stdbool.h'
In case of building with minimal libc (provided by Zephyr)
we rely on minimal libc headers and manually specify
toolchain's C header directory (as minimal libc still uses some
toolchain's C headers.

The MWDT compiler can replace some code with call to builtin
functions. We can't rely on these functions presence if we
don't use MWDT libc.

MWDT toolchain has Stackcheck_alloca option enabled by default.
So it adds stack checking in addition to Zephyr's stack checking.
As it is completely redundant let's drop it.

This commit converts the MWDT compiler implementation from the old
macro based approach and into the new toolchain property scheme.

* add metaware toolchain support in build system:
* compiler
* linker
* binutils
* gcc objcopy is used because it can't be replaced
with mwdt's binutils currently
* To use ARC metaware toolchain, you'd better:
* in Linux/Unix environment
* install arc gcc/zephyr toolchain to use gnu's objcopy
tool
* set ZEPHYR_TOOLCHAIN_VARIANT=arcmwdt
