Fix T86601: Cycles accumulates displacement when transforming an Object
In order to update the BVH when only the transformations are changing,
we would tag the Object's Geometry as modified. However, when
displacement is used, and the vertices were not themselves modified,
this would cause us to redo the displacement on already displaced
vertices.
To fix this, use a specific update flag for detecting and notifying that
transformations were modified.
