The vhost driver uses work_queue() for deferred probe but was missing
the SCHED_WORKQUEUE Kconfig dependency, causing link errors on boards
that don't enable workqueue by default.

Change DRIVERS_VIRTIO and DRIVERS_VHOST from menuconfig to hidden config
options. Each virtio/vhost sub-driver now automatically selects its parent
config, eliminating the need to manually enable DRIVERS_VIRTIO or
DRIVERS_VHOST in defconfig files.
This simplifies board configuration by removing redundant CONFIG_DRIVERS_VIRTIO
entries from affected defconfig files.

virtio is a framework to implement the virtio drivers
vhost (Virtual Host) is a framework to implement the virtio devices
With the virtio and vhost framework, we can use the virtio drivers
and vhost drivers to implement the cross-core communication.
