The issue was that the `object_is_geometry` method was used in two different
contexts that expected the function to behave differently. So a recent change
that fixed `object_is_geometry` for one context, broke it for the other context.
The two contexts are:
* Check if a "real" object can contain a geometry to check if it has to be tagged
for sync after an update.
* Check if an object/instance actually is a geometry that cycles can work with.
I created a new `object_can_have_geometry` method for the first use case, instead
of trying to adapt the existing object_is_geometry method to serve both uses.
Additionally, I changed it so that a BObjectInfo is passed into `object_is_geometry`
to make it more explicit when this method is supposed to be used.
