Ice anomaly spawns ice underneath it (#21227)

* added TileAnomalySystem to AnomalyIce

* added FloorIce for station

* created ice crust entity to spawn under ice anomaly

* update draw depth for ice crust

* uh oh, added ice-sliding but at what cost

* resolved mispredicts

* updated sprite alpha, removed appearance component (not used)

* fixed function not reflecting event name, left datafield attributes blank, added one comment about saving data (?)
