feat(datatables): move the data table permissions endpoints to the enterprise edition

Browse Source 
The permissions read, save and usable-roles handlers move to
windmill-ee-private; the routes stay registered and, without the enterprise
edition, answer that data table roles are an Enterprise Edition feature.
ensure_governs_datatable and ensure_reaches_datatable keep their paths: the
first refuses, the second passes a data table not under roles.
