MetaWare toolchain doesn't support building Zephyr with
Picolibc module. This PR fixes biuld process by turning off
picolibc support on compiler side.

On very early stage build system needs to get access to DTC preprocessor.
MWDT has no it's own preprocessor, so here zephyr-SDK preprocessor is used.
On latest build stages zephyr-SDK objcoby also required as MWDT binutils
don't support all features. This at the same time requires that
ZEPHYR_SDK_INSTALL_DIR must be initialized with valid arch-dependent
prefix.
Zephyr-SDK requires ARCH variable to be initialized before
include "generic.cmake", but in hew HWMv2 model ARCH variable will be
initialized more later. This workaround uses any (first awailable,
independent on ARCH) toolchain from SDK for DTC preprocessing only.
For other build stages ARCMWDT will be used.

Cleanup ARC MWDT search path handling:
* Don't print warning if ARCMWDT_TOOLCHAIN_PATH is missing but
METAWARE_ROOT is set. Treat it as valid case and do message
with status level instead of warning.
* Make rest of the error messages more understandable for users.

As of today MWDT toolchain in case of Zephyr may use few
tools from GNU toolchain - GNU compiler for DTS preprocessing
and objcopy for section renaming.
Currently we were trying to find any GNU compiler & objcopy
which start to cause compatibility issues for new targets -
i.e. not every objcopy knows new ARC targets.
Let's use ARC GNU tools from Zephyr SDK as we still usually
require it when building with MWDT for other tools like DTC
(device tree compiler)

Fixes: #40389
Update toolchain handling to use zephyr_get() to ensure consistent
handling of CMake cache variables, environment variable, and CMake
local variables.

* 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
