The problem this solves is that 90% of the jobs of the libc++ CI pipelines are otherwise Clang jobs, which makes it nearly impossible for libc++ to figure out information about the jobs we're actually running.

In particular, I would like to avoid bikeshedding the location of the `generate-buildkite-pipeline` scripts under `.ci` -- it doesn't matter, I just wanted a neutral (non-libcxx-specific) location and that can be changed later once CI has stabilized.

Please excuse my ignorance, but does this change precommit CI test coverage when reviews are created/updated? e.g., if a review goes up with changes only to Clang, will the review still get a libc++ test run to ensure the Clang changes don't break libc++?
