drivers/virtio and vhost: auto-select parent config from sub-drivers

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.
