Remove obsolete ProvideCodeBase and ProvideBindingRedirection attributes

[jcansdale]

• GitHub Extension for Visual Studio version: 2.5.2

Now that #1236 has been merged, the ProvideCodeBase and ProvideBindingRedirection attributes should no longer be needed. This is good because maintaining them was error prone. Any new dependencies of an assembly with one of these attributes also required an attribute (they're viral). Forgetting to do this would lead to difficult to diagnose runtime errors. 😭

It's time to get rid of them!
