The current deprecation warning could give the impression that
CROSS_COMPILE is deprecated, which is not the case.
Instead it is the behavior of defaulting to `cross-compile` when
setting CROSS_COMPILE in environment without setting
ZEPHYR_TOOLCHAIN_VARIANT that is deprecated.
Not the use of `CROSS_COMPILE` setting itself.

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

Move deprecated XCC_USE_CLANG setting to deprecated module.
Deprecated and move the use of CROSS_COMPILE to deprecated module as we
have had ZEPHYR_TOOLCHAIN_VARIANT==cross-compile for a long time.
Deprecated code is now loaded with a single line:
> find_package(Deprecated COMPONENTS XCC_USE_CLANG CROSS_COMPILE)

The deprecated CMake module allows Zephyr to move deprecated code to a
centralized location from where it's both easy to get an overview of
deprecated code, and remove the code when it has been deprecated long
enough.
It further improve existing code, as the real CMake code now can be
changed from n-lines of deprecated code into a single line of the form:
find_package(Deprecated COMPONENTS <deprecated_name>)
