block: Add 'x-blockdev-del' QMP command
This command is still experimental, hence the name.
This is the companion to 'blockdev-add'. It allows deleting a
BlockBackend with its associated BlockDriverState tree, or a
BlockDriverState that is not attached to any backend.
In either case, the command fails if the reference count is greater
than 1 or the BlockDriverState has any parents.
