Initialize bigint conversion for packages_build_infos

This is the first step to convert pipeline_id related to bigint for:
- packages_build_infos.pipeline_id

See https://docs.gitlab.com/ee/development/database/avoiding_downtime_in_migrations.html#initialize-the-conversion-and-start-migrating-existing-data-release-n
