cmake: unittest: set -Wshadow

fabiobaltieri · henrikbrixandersen · commit 32323544565e · 2025-09-26T13:24:30.000+02:00
Set -Wshadow when compiling unit tests, this way we can test macro
combinations and ensure they don't generate shadowed variables, which
would generate a warning by default in normal Zephyr builds.
