Make setMaintainVisibleContentPosition and MaintainVisibleScrollPositionHelper internal

Summary:
`setMaintainVisibleContentPosition` takes a `MaintainVisibleScrollPositionHelper.Config` parameter whose constructor is `internal`, making the method uncallable by OSS consumers. This change makes both the method and the helper class `internal` to reflect that reality and reduce the public API surface.

Changelog: [Internal]
