Don't try to set any ACL on uploaded objects

Closes #59309

See merge request gitlab-org/gitlab-ce!26781

Set ACL of uploaded objects to not-public (fog-aws) or no ACL at all
(fog-google).  Value is ignored by other supported backends (fog-aliyun,
fog-openstack, fog-rackspace)

This allows uploads to GCS with ACL support disabled.

The main point of this check is to ensure we aren't checking
all branches, not that we have an exact count.

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/24034 introduced
a regression where only the first 20 branches were used to determine
whether a branch has been merged because the pagination was applied
incorrectly. Requesting the second page of branches via the API would
always have the wrong merge status. We fix this by properly paginating
the branches before requesting their merge status.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/56250

Fix failing spec in spec/features/users/login_spec.rb
