Subject: [PATCH 1/4] [libc++] Move the check-generated-files job to Github
 Actions

This allows running these quick checks faster than in our Buildkite
pipeline, which has much more latency. This will also avoid blocking
the rest of the testing pipeline in case the generated-files checks
are failing.
