Add |IsNotIn| EraseIf-helper and convert to in-place set-intersection

There are a few places where the Omnibox and friends need set-intersection
but they currently construct a new set doing so. With EraseIf and this
IsNotIn helper, it's trivial to do in-place set-intersection. It showed a
20% improvement under micro-benchmarks.

This patch includes an existing Omnibox conversion, plus one under
components/bookmarks.
