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.

This index is required to allow fast retrieval of recent push events
without merge requests. Without this index in place the query would
lead to PostgreSQL scanning over 150 000 index entries all the time,
easily taking up between 200 and 500 milliseconds. This index
reduces the time spent in this process to around 40 milliseconds on
GitLab.com.
