Let artifacts declare that they use content-based paths.

This is basic infrastructure for supporting --experiment_output_paths=content. This change does not implement any actual uses.

The intention is that we can incrementally opt in content-mapping support, i.e. rules can declare which of their outputs should do content mapping. The first test goal will be to opt in java_library compilation.
