Add support for using "Label Templates" (like Display Templates and Editor Templates)

### Is your feature request related to a problem? Please describe the problem.

I work on a project with many custom `DisplayTemplates` and `EditorTemplates`. So far, the default label generated by using `LabelFor` has been sufficient for, but now I'd like to implement custom labels.

### Describe the solution you'd like

When using e.g. `@Html.LabelFor(x => x.MyProperty)`, where `MyProperty` is of type `MyModel`, I'd like for the the HtmlHelper to check if `~/Shared/LabelTemplates/MyModel.cshtml` exists and render that view instead of a default label. (Basically for `LabelFor` to behave just like `DisplayFor` and `EditorFor`.)
