Adding support for custom discovery of IRouteFactory

The new IDirectRouteProvider api supports discovering IRouteFactory
on controller descriptors and action descriptors with arbitrary criteria.

DefaultDirectRouteProvider is given as a base class for customizing a
single aspect of the process.

Since criteria for whether or not an action/controller is attribute
routed is now arbitrary, I've added a marker to the descriptors. This
required some refactoring of the action selector, now caching proceeds in
two phases.

1. Existance of actions and descriptors are cached
2. Details used for action selection are cached.

2) will happen when requests come in, so attribute routing is allowed to
mark the descriptors before they are cached.

Fix CodePlex bug: https://aspnetwebstack.codeplex.com/workitem/1658

Url.Action overloads (and similar) ignore inherited properties.

This fix affects both WebAPI HttpRouteValueDictionary,
Overloads that take anonymous objects to construct a routevaluedictionary
and overload that takes anonymous objects to create HtmlAttributes.

The fix reverts the behavior to MVC5/WebAPI2/WebPages3 behavior where it will allow for derived properties to show up.
But it maintains the performance characteristics of MVC5.1/WevAPI2.1/WebPages3.1.
