Offer Shell completion for top-level packages without subpackages
`bazel build //` now completes to `bazel build //:` when there are no packages beneath the top-level package. While this is mostly an edge case that doesn't apply to real projects, it will become more relevant when completion support is added for external repositories in a future PR.
Closes #20679.
