fix(ivy): ensure host bindings and host styling works on a root component (#28664)

Prior to this fix if a root component was instantiated it create host
bindings, but never render them once update mode ran unless one or more
slot-allocated bindings were issued. Since styling in Ivy does not make
use of LView slots, the host bindings function never ran on the root
component.

This fix ensures that the `hostBindings` function does run for a root
component and also renders the schedlued styling instructions when
executed.
