Provide data structures to capture a timestamp in two different
clocks, monitor the drift between those clocks, and using a base
instant with estimated drift convert between the clocks.
This provides the core technology to convert between system uptime and
an external continuous time scale like TAI (UTC without applying leap
seconds).

This commit is a followup to PR #25808 which updates the tests to
ensure the REQUIRED keyword is also used for the ZephyrUnitest package.
This provides a better error message when building with CMake and
forgetting ZEPHYR_BASE or not registering Zephyr in the CMake package
registry.

cmake: use find_package to locate Zephyr
breaks as we don't find the ZephyrUnittest package. For now revert to
the old means until a proper fix can be made.

Using find_package to locate Zephyr.
Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.
Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.
It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.

We don't have to build an image for running test timeutil. We
can just build a native app to test it. So move it into "unit"
directory.
Also, add 64-bit support for unit testing framework.
