Version 2 of context types:

https://lists.oasis-open.org/archives/virtio-dev/202108/msg00141.html

Changes since RFC:
   * le32 info --> {u8 ring_idx + u8 padding[3]).
   * Max rings is now 64.

Changes since v1:
   * Document plan regarding context types + display combinations that
     need implicit sync in patch 9 commit message.
