Previously, coverage would have to be collected using the explicit `_with_debug` targets:
```
bazel coverage //src/mongo/platform:visibility1_test_with_debug
```

The non-suffixed targets would run (test), but did not collect any coverage since the debug info was not there:
```
bazel coverage //src/mongo/platform:visibility1_test
```

*Now, those plain targets get the debug info they need for coverage runs; no more wrangling with derived suffixes.*

No performance implications to `bazel build` and `bazel test` since this is all in the analysis phase.

This is a stepping stone towards getting bazel coverage on resmoke suites.
