Fix setting share_with_group_lock

Closes #37916

See merge request gitlab-org/gitlab-ce!14300

Prior to this commit running
Namespace#force_share_with_group_lock_on_descendants would result in
updating _all_ namespaces in the namespaces table, not just the
descendants. This is the result of ActiveRecord::Relation#update_all not
taking into account the CTE. To work around this we use the CTE query as
a sub-query instead of directly calling #update_all.

To prevent this from happening the relations returned by
Gitlab::GroupHierarchy are now marked as read-only, resulting in an
error being raised when methods such as #update_all are used.

Fortunately on GitLab.com our statement timeouts appear to have
prevented this query from actually doing any damage other than causing
a very large amount of dead tuples.
