This moves selectability/visibility flag flush from some hardcoded places in the code to depsgraph. This way it is possible to simply tag depsgraph to update those flags and rest it'll do on its own. Using depsgraph for such flush is an overkill: those flags are fully static and can not be animated, so it doesn't really make sense to hook only those to depsgraph. However, in the future we will have overrides on collections, which ideally would need to be animatable and drivable and easiest way to support this is to do this on depsgraph level, so it ensures proper order of evaluation for animation and drivers. And it seems logical to do both overrides and flags flush from depsgraph from this point of view. This commit also includes the evaluation of IDProperty for collections, which basically are just another form of override. So once we implement the other kind of overrides the flushing and collection evaluation won't change. Patch by Sergey Sharybin and Dalai Felinto
