block: Remove legacy async I/O API

Browse Source 
Drop the borrowed iovec AsyncIo entry points now that all callers use
owned operations. Rename the transitional owned batch and completion
methods to the final trait names and remove the borrowed submission
helpers from the queue wrappers.

This removes a bunch of known safety foot-guns so future-us don't
accidentally use them.
