Allow only one runner profile active at once in examples and archetypes

Since only one SLF4J logger binding is allowed in the classpath, we shouldn't allow more than one runner profile to be active at once in our examples/archetype modules since different runners use different bindings.
Also, remove slf4j-jdk14 dependency from root and place it instead in direct-runner and dataflow-runner profiles, for the same reason.

Subtask of issue #18244

Start by inspecting the Maven profile definitions in the examples and archetype modules, then locate the root slf4j-jdk14 dependency and the direct-runner and dataflow-runner profiles. Done means the profiles prevent multiple runner profiles from being active together and slf4j-jdk14 is scoped only to the two specified runner profiles.
