.github: manifest.yml: Add CI labels based on modules in west.yml

Add CI labels only when relevant modules are changed.
This allows more granularity on the testing when west.yml is changed,
allowing different test suites to run depending on the module,
instead of running the entire test suite whenever west.yml is updated.
