Automated rollback of commit 9b420b5.

*** Reason for rollback ***

Incompatible pipeline still showing failures: https://buildkite.com/bazel/bazelisk-plus-incompatible-flags/builds/1320

Need to investigate why some fixes @Head seem not to work.

*** Original change description ***

Roll forward 1fdc628: default --incompatible_config_setting_private_default_visibility to true

This was rolled back in d4fc6db
due to failing Bazel downstream tests. I fixed as many as I was aware of: see latest comments on #12933.

Fixes #12933.
