Update Fortunes to use Razor templating

[DamianEdwards]

UPDATED: This has been updated on top of @roji's UTF8 changes. Please take a look!

Updates the Fortunes implementations for Minimal and Platform to use Razor .cshtml templates with custom base classes intended for rendering without MVC.

Minimal Results

The new Fortunes Razor implementation for Minimal APIs shows an 88% improvement, possibly due to a large reduction in lock contention and more efficient rendering (e.g. no int.ToString(), optimized HtmlEncoder settings, etc.):

Platform Results

The new Platform-level Fortunes Razor implementation shows a drop of only 2.4% from the previous non-templated platform implementation from before @roji's UTF8 changes, and still above 460K RPS:

Might as well just return Task here and then pass through in the other methods if you are just going to await in those ones?

[halter73]

Those methods also need to await the LoadFortunesRows() calls so you can't just return the Task.

[benaadams]

nvm you have to await anyway
