As part of aosp/3022586 where we added the idea of "test-only" modules
and top_level_test_targets, this CL implements that for cc_ modules.
We let users set "test-only" on cc_library, but not on other modules
where the module kind is implicitly test-only, like cc_test.
Here the implementation, not the user decides it is test-only.
