Updated the default arc generation for tree markers.
Now updates the arc height based on the DecorScale (since some trees are now being scaled dramatically and squishing all the tree markers to the bottom of the tree).
Added some editor buttons for assigning default arcs and updating marker data (also supports multi select).
Updated tree entity gizmos to show a box showing the players relative size to the tree after decor scale will be applied at runtime. This helps with quickly spotting trees that will have issues when scaled.
Regenerated tree marker data for all trees.
