Prevent errors from comment node roots with enableViewTransition (#33205)

We have many cases internally where the `containerInstance` resolves to
a comment node. `restoreRootViewTransitionName` is called when
`enableViewTransition` is on, even without introducing a
`<ViewTransition />`. So that means it can crash pages because
`containerInstance.style` is `undefined` just by turning on the flag.

This skips cancel/restore of root view transition name if a comment node is the root.
