Fixes: #73831
find_package(Zephyr) should be called before first project() call.
Zephyr package will test and force-set the correct toolchain, especially
the C compiler.
The project() will also set the C compiler, if not set already.
If project() is called first, then conflict arises on the C compiler
selection and thus the following message is seen:
> You have changed variables that require your cache to be deleted.
> Configure will be re-run and you may have to reset some variables.
> The following variables have changed:
> CMAKE_C_COMPILER= /usr/bin/gcc
This cache deletion results in other errors, such as a missing BOARD
setting.

Fix the deprecated calls to loading ZephyrUnittest by replacing them
with `Zephyr COMPONENTS unittest`.

Adding cmake_minimum_required() as this is required by CMake.
CMP0000 is a deprecated policy which allows to omit this function call,
however doing so will result in CMake printing a warning.
Adding cmake_minimum_required() to tests missing this call will remove
the warning and also allow us to remove the policy setting.

The test infrastructure uses EXTRA_CPPFLAGS to control which
configuration is used, but this was also added to CMakeLists to ensure
a common optional infrastructure was always available. Since unit
tests don't use Kconfig, this actually prevented the test variants
from being selected.
Add the flag in the test itself, which works correctly since the test
includes the implementation directly.

cbprintf should not pull in stdio.h unless it needs to, specifically
to get the FILE type for prototyping the stream substitutions. The
unit test assumes that these functions are always declared. For unit
testing where Kconfig isn't involved we need to tell the build system
to always provide them.

Tests for most paths through the conversion infrastructure. Expected
output can be validated with the host libc by setting USE_LIBC within
the source.
