[8.x] Use View contract when rendering Blade components

[inxilpro]

Right now ManagesComponents uses Illuminate\View\View rather than Illuminate\Contracts\View\View which means that components that return a different implementation of the View contract break Blade components.

The only code that uses this import is:

if ($view instanceof View) {
    return $view->with($data)->render();
}

Since with() and render() are both on the view contract, it should be completely safe to swap the implementation for the interface.
