It is not allowed to do tagging or updates while dependency graph is in the middle of evaluation. This is something what is simple to violate from python code. This change adds some sanity checks. The request to update view layer or dependency graph will raise an exception in Python now, so it's easy for scripters to notice. Tagging for update will do silent return unless running with debug command line argument. This is because it's a bit tricky to know which exact dependency graph corresponds to a context from which an update tag was triggered. Differential Revision: https://developer.blender.org/D6035
