ci: add build for each log level

Created by: tgonzalezorlandoarm

The CI is only testing the build for the default log level. Add a parameter "ll" (log-level) to test the builds with a specified log level. This is done so that multiple runs of the ci_cmake tests can be done in parallel by calling this script multiple times with the different log levels. These changes are done while improving the readability of the constructor calls of Build() with the different optional parameters.
