cmake/zephyr: move auxiliary modules like math earlier in build rules

Split the build directory listing into two. First introduce directories
that add auxiliary modules to the build. These directories provide
modules that may be used by other modules. Then a second list for all
other directories.

This split avoids dependency issues with llext modules that require
auxiliary modules to be introduced first.
