tests: logging: Add test for stack usage characterization

Added test which estimates stack usage of few types of logging
messages in various modes, with and without optimization. Test
was used to determine usage for various architectures and is expected
to be used to detect stack usage increase since it fails when
stack usage in given configuration goes beyond the hardcoded limit.
