Fixes: #18637

Using the old namespace `http://xamarin.com/schemas/2014/forms` was
causing a NRE:

    System.NullReferenceException: Object reference not set to an instance of an object.

In f939049, I inadvertently introduced this NRE, but even after fixing
it, I would instead get:

    FormsNamespace.xaml.sg.cs(15,48): error CS1001: Identifier expected

Due to the namespace, type, and base type all being `null` in this case,
the generated C# is invalid.

Instead of generating C# *at all*, let's emit an error message that says
to use the correct namespace.

I also provided a `Location` for the error message, so we will now know
what file the error originated from.

I attempted to write some test here, but adding an invalid file like
this causes the XAML unit tests project to fail to build. It feels like
we actually need to create a unit test project for the source generator
-- as there isn't one now.

* Add `[Obsolete]` to `FormsUri`
