ilo: replace cp hooks by cp owner and flush callback
The problem with cp hooks is that when we switch from 3D ring to 2D ring, and when there are active queries, we will emit 3D commands to 2D ring because the new-batch hook is called. This commit introduces the idea of cp owner. When the cp is flushed, or when another owner takes place, the current owner is notified, giving it a chance to emit whatever commands there need to be. With this mechanism, we can resume queries when the 3D pipeline owns the cp, and pause queries when it loses the cp. Ring switch will just work. As we still need to know when the cp bo is reallocated, a flush callback is added.
