[shimV2] [VM controller] refactor + adds Update + Device controllers (#2663)

* [shimV2] remove all interfaces from vm manager and guest manager

Following the shim V2 standard, we are declaring the interfaces at the place where the APIs are used. Therefore, we are deleting all the interfaces from the existing packages.
