Refactor GrowthHack to always render on iOS with enabled prop (#9723)

Drill down an `enabled` prop to ThreadItemAnchorFollowButtonInner so
that the GrowthHack wrapper is always rendered on iOS, even when the
follow button shouldn't be displayed. The inner component returns null
when disabled, allowing GrowthHack to render its logo without children.
