Modifiers: Only allow geometry nodes for curves and point cloud 

Effectively this disables two volume modifiers for the new curves
object and the point cloud object types. The aim is to simplify the
process of using these object types to prove out a node-group-based
workflow integrated with the asset browser. We're making the assumption
that these two modifiers were used very rarely on the new curves type
since that wasn't its purpose, so this breaks backwards compatibility.
