Unify TableMixin and GeoJsonMixin features

[nf-s]

We have a bunch of tickets related to adding more table styling features to geojson, and more geojson features to table styling.

Ideally we have a single core Mixin that is responsible for all 2D vector data visualisation.

• #5569
  • This would include adding support for a geom column (for example using WKT - well known text format)
• #6802
• https://github.com/TerriaJS/terriajs/issues/6963
• https://github.com/TerriaJS/terriajs/issues/6809

I also think we should remove older non table styled geojson features (see forceCesiumPrimitives)
