I might be wrong about this but I believe Inherited is entirely a runtime concern, reflection (and maybe the clr type system) takes it into account when queried. |

Closes #9256 by checking all super types of an attribute for AllowMultiple.
This is done by creating a sequence of types that need to be checked for AllowMultiple, and walking that sequence until one of them returns a concrete value for AllowMultiple. This is a pretty simplistic strategy, and I'm not sure how it interacts with the
Inheritedproperty of AttributeUsage. I've added a test case as well to prove that this works as expected, though I could certainly use some additional test cases to ensure this works across all cases. If there is more logic necessary to takeInheritedinto consideration, it should be pretty easy to stop the type-hierarchy traversal just by returning aSomevalue at that level, which would satisfy thetryPick.
