[RelativePositioning] Never fail to move nulls
What does this MR do?
This addresses #238416 (closed), in specific errors such as https://sentry.gitlab.net/gitlab/gitlabcom/issues/1766076 where NoSpaceLeft is raised when moving nulls.
This is addressed in this MR in two ways:
- we try harder to make enough space. Up to 10 gaps will be consolidated to make enough space.
- we stack overflow elements at the edge rather than failing
