Notify Renderer components of mesh geometry change.
By default, whenever Mesh data changes that could affect the geometry of the mesh, all Renderer components that use
this mesh get notified. For example, MeshRenderer components recalculate their bounding boxes, and ShapeModule
rebuild internal data used for mesh surface emission.
However a MeshUpdateFlags.DontNotifyMeshUsers flag can be used in Mesh.SetVertexBufferData,
Mesh.SetIndexBufferData or Mesh.SetSubMesh in order to skip this notification.
This can be beneficial when you know that many mesh modifications will happen before the
renderer components will need to actually update. A manual call to MarkModified can be used later
to notify the dependent renderer components of a mesh geometry change.MarkModified function only needs to be called if you actually use the DontNotifyMeshUsers flag. In all other cases
the mesh change notifications happen automatically.
