Re-organize TypeScript ambient modules

Even though this release has breaking changes. It will not impact you, unless your app was using imports not documented on the website. We have renamed the following TypeScript ambient modules

• @ioc:Adonis/Lucid/Model -> @ioc:Adonis/Lucid/Orm
• @ioc:Adonis/Lucid/Relations -> @ioc:Adonis/Lucid/Orm
• @ioc:Adonis/Lucid/DatabaseQueryBuilder -> @ioc:Adonis/Lucid/Database
