Add Dispute IDs everywhere

[tgrigsby-sc]

This adds dispute ID everywhere it was missing and takes advantage of @jeffdefacto's lua magic to no longer need to do any of the disputed border cutting we were doing before.

NE dispute_ids

• update NE.jinja to export components for dispute_id
• update boundaries.yaml to export components for dispute_ids for NE-zoom features

OSM dispute_ids

• Change the filter that exported mz_internal_dispute_mask to just export a disputed_reference_line instead. The other code path will now handle applying all the right dispute-related properties.

• remove all the code for handling mz_internal_dispute_mask since it is no longer needed.

• [X] Update tests

• [ ] Update docs

@nvkelso Looks like the disputed borders cutting is still needed - we're seeing partial overlaps of border pieces with disputed pieces. Alas! Someday we can remove this.
