Geometry Nodes used a `PropertiesVectorSet` in some places to allow
constant-time `IDProperty` access by name in a group. This used to be a
bottleneck in node groups with hundreds of inputs. Now this separate hash table
is not necessary anymore, because it's `IDProperty` groups now support this
directly since 6cb2226f13.
This also adds a `IDP_GetPropertyFromGroup_null` utility function to be able to
do this refactor more safely. Null pointers were allowed before.
