testutils: add skip.UnderBazel and skip.UnderBazelWithIssue

This is to skip individual tests under bazel. This seems a bit more
fine-grained than the broken_in_bazel tag in the bazel configuration
but also allows us to avoid skipping tests that work outside of bazel
in our main test suite.

Release note: None
