Torsten Rasmussen 8e929fd20c cmake: find_package to honor list of zephyr installations to prefer
This commit introduces ZEPHYR_PREFER which is a list that user can
specify when compiling an application.

This allows a user who has multiple Zephyr installations in the same
work-tree to provide a list of which Zephyr to prefer.

This is an extension to CMake VERSION field, as a user who is working
with multiple Zephyr installations could face a situation where multiple
Zephyr's is having same version, as example 2.2.99, in which case CMake
version is not sufficient.

Example, workspace looking as:
/projects/workspace/zephyr
/projects/workspace/zephyr-alternate
/projects/workspace/zephyr-wip
/projects/workspace/my_app

To prefer zephyr-alternate, then zephyr-wip the my_app/CMakeLists.txt
should look as:
set(ZEPHYR_PREFER "zephyr-alternate" "zephyr-wip")
find_package(Zephyr)

Torsten Rasmussen 8829e8237a cmake: ZephyrUnittestConfig.cmake added
Adding ZephyrUnittestConfig.cmake and ZephyrUnittestConfigVersion.cmake
to allow unittest projects to use find_package to locate ZephyrUnittest.

This means that it will be possible to allow users to run CMake without
the need to source zephyr-env.sh or run zephyr-env.cmd.

Torsten Rasmussen caf596ef1b cmake: Zephyr package now sets ZEPHYR_BASE as cmake cached variable
This commit introduces ZEPHYR_BASE as a cached variable, ensures that
once ZEPHYR_BASE has been set in a project, it is sticky.
Using cached variable also allows users to reconfigure ZEPHYR_BASE if
they so wish.

Torsten Rasmussen 555eb9b5dc cmake: detection and using a not registered Zephyr repository package
This commit adds the possibility of using a Zephyr repository package
base even when it has not been exported to CMake package registry.

It also introduces the possibility of locating and using Zephyr
CMake config package correctly when invoking CMake on an out-of-tree
project.

Torsten Rasmussen 3dd96d8927 cmake: Added possibility to disable the printing of version
When ZephyrConfig package is being version checked, then
ZephyrConfigVersion.cmake loads version.cmake.

This causes a print message, such as the following to happen:
-- Zephyr version: 2.2.0

Now, in case a user has multiple Zephyr installations, this could
result in something similar to:
-- Zephyr version: 2.2.0
-- Zephyr version: 2.x.0
-- Zephyr version: 3.x.0
being printed.

This commit add the possibility to disable version printing.

With new Zephyr base find_package, printing of ZEPHYR_BASE is added
after the version, in order to make it easy for users to see which
Zephyr is used.

Torsten Rasmussen 81007172a4 cmake: adding ZephyrConfig.cmake to allow an easy way to locate Zephyr
Adding ZephyrConfig.cmake and ZephyrConfigVersion.cmake allows projects
to use find_package to locate Zephyr.

This means that it will be possible to allow users to run CMake without
the need to source zephyr-env.sh or run zephyr-env.cmd.

This is especially useful for IDEs such as Eclipse or SES, where it will
no longer be required to source the above files before launching the
IDE.
