Checkin VS modifications to kproj

My up-to-date VS wants these projects to have port numbers. Makes sense
because they are web projects.
[Fixes #393] [Design] Update ViewComponent result apis to be consistent with Controller

1. Updated ViewComponent to exposes similar properties to the existing ones in controller where
appropiate. We've left out Resolver for being a bad pattern (just inject the dependency on the constructor
or use Context.RequestServices to access it if needed) and Response as although available through the Context
property, it shouldn't be used/modified in a ViewComponent.

2. Updated ViewViewComponentResult to follow a similar pattern as ViewResult where the constructor is
parameterless and elements like ViewEngine are resolved during execution if the user does not set the
associated property on the object.

3. Updated ExecuteAsync in JsonViewComponentResult to remove the unnecessary pragma and async keyword from the
signature and to use Task.FromResult(true) instead.

4. Cleaned up ViewViewComponentResult tests.
