virtio-console: Fix VIRTIO_CONSOLE() cast macro

Commit 0399a3819b27083ba69b88a9baa9025facab85bd (virtio-console: QOM
cast cleanup for VirtConsole) broke virtserialport since it shares
functions and state struct with virtconsole. Let virtconsole inherit
from virtserialport, and use virtserialport type for casting.

Note that virtio-serial-port is the abstract base type in
virtio-serial-bus.c, whereas virtserialport is the user-instantiatable
type in virtio-console.c. Therefore using TYPE_VIRTIO_CONSOLE_SERIAL_PORT.
