add loads for cc rules to BUILD files

[benjaminp]

builtin rules are removed in newer versions of Bazel

@johnbartholomew this PR is needed to use jsonnet/go-jsonnet with Bazel 9. Do you think we could get it merged?

Sorry for the delay in reviewing this. Two notes:

• It looks like rules_shell also needs to be added as a dependency in MODULE.bazel (it is used to run the test suite)
• Please update the bazel lockfile (you can do this with bazelisk mod deps --lockfile_mode=update)

[johnbartholomew]

Could you also sync with master (rebase ideally, but merge if you prefer)? I have updated the CI workflow to check multiple Bazel versions for the example of using the library with bazel, and it would be good to confirm that v7, v8, and v9 all work with this PR (currently on master v7 and v8 work but v9 does not, as noted in mortenmj's comment)

[benjaminp]

Thank you for the review. I have added rules_shell, merged master, and synced the lock file.

Rebased for linear history, and merged. Thanks!
