Add Fortunes endpoint that returns RazorComponentResult to the Minimal project

[DamianEdwards]

This will allow for easy investigation of performance differences between:

• Razor Pages
• MVC with Razor Views
• Blazor SSR
• Razor Slices & Minimal APIs
• Razor Components & Minimal APIs (RazorComponentResult)
  • !!NEW!! Having the endpoint handler read from the database and passing in the model via parameters
  • Having the component read from the database itself (in the BlazorSSR project already)

Also added a way to run Fortunes in the Minimal project without a database (similar to what we have in Platform) to more directly compare the rendering stacks.

For the RazorComponentResult there's a commented-out line that uses a custom parameters struct that implements IReadOnlyDictionary<string, object?> to pass the model to the component to avoid allocating a Dictionary<string, object?> on every request. Figured it was interesting to leave that there for whomever takes up doing deeper analysis here.
