Add CRUD tooling for Organizations
## Problem statement We need the ability to create, modify and delete Organizations. Some of these capabilities already exist but we need to determine how to expose them to users outside of the current feature-flagged experience Most important/urgent is the need to delete an Organization, eg. as part of the reconciliation/confirmation process for auto-created backfilled Organizations. The unwanted orgs (eg. once empty of TLGs) should either be permanently deleted, or perhaps archived in a hidden state. ## Exit criteria * It should be possible to delete or archive an Organization, such that it no longer appears visible except to Owners: https://gitlab.com/groups/gitlab-org/-/work_items/21433+ * It should be possible to create and modify existing Organizations through a simple UI available to Owners ## DRI @rymai <!--STATUS NOTE START--> <!--STATUS NOTE END-->
