fix: allow_to_create_new_org checks org autocreate [FC-0076] (#36094)

Updates the StudioHome API's allow_to_create_new_org to require both organization-creation permissions and ORGANIZATION_AUTOCREATE to be enabled. It also adds the list of "allowed organizations for libraries" to the Studio Home API so that the Authoring MFE can use it.
