Don't focus the omnibox when a subframe navigates on NTP (Merge to M58)

Don't focus the omnibox when a subframe navigates on NTP (Merge to M58)

This fixes a bug where an NTP replacement page from an extension was
losing focus to the omnibox when a subframe on that page committed a
navigation.  So if the user was typing into an <input> on the NTP
replacement page while a subframe navigated, the focus was
disruptively shifted to the omnibox in the middle of typing.

This matters only in OOPIF modes, as focusing of the omnibox was done
in RenderFrameHostManager::CommitPending, which is only used for
cross-process commits.
