Some hypervisors, e.g. UML, negotiate a queue size larger than `QUEUE_SIZE`
(128), which results in failures. This patch allows users to specify it
using `--max-queue-size <size>`.

For the purpose of "namespacing" them under the enum type.
While at it, move QUEUE_SIZE and NUM_QUEUES as related constants for
VhostUserConsoleBackend.

Since we know the unknown event value, we might as well specify it in
the error message of Error::HandleEventUnknown to help users and
developers.
While at it, return an error when trying to access vrings with
`device_event` >= QUEUE_SIZE.

std::convert::From is included in the prelude, so no need to refer to it
by its full path.

Human readable text for this error variant was copied from
CouldNotCreateBackend, so adjust it for its own purpose.
Fixes: c739770 ("vhost-device-console: use worker's epoll for input events")

The current implementation seems ready to be promoted to the
main workspace since the device supports test coverage have been
increased and the basic functionality is implemented.
Cargo.lock files both in main and staging workspaces are updated.
Support for VIRTIO_CONSOLE_F_SIZE and VIRTIO_CONSOLE_F_EMERG_WRITE
is still missing.
