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)

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.

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.
