Add support for @(InternalsVisibleTo) items that turn into assembly attributes
Given that `InternalsVisibleTo` (IVT) is such a common assembly-level attribute, this adds support for specifying it directly via simple items, such as: ``` <ItemGroup> <InternalsVisibleTo Include="MyLibrary.Tests" /> </ItemGroup> ``` Optionally, a `Key` metadata can be specified to provide a strong-named IVT: ``` <ItemGroup> <InternalsVisibleTo Include="MyLibrary.Tests" Key="PUBLIC_KEY" /> </ItemGroup> ``` The targets will also use automatically a `$(PublicKey)` if available and no `%(Key)` metadata override is found. Otherwise, it will default to an IVT without a key. This also avoids having to learn the `_Parameter1` syntax in `AssemblyAttribute` elements, and is more similar to the way other higher-level properties like `AssemblyTitle` or `Product` are also turned into assembly attributes. To turn off this feature, set `$(GenerateInternalsVisibleToAttributes)` to `false`. Partially fixes #3166
