.NET 6 update: prefer new Use middleware extension method

[Rick-Anderson]

Add a new app.Use overload that requires users to pass the HttpContext to the next function which will save 2 per-request allocations over the previous extension method.

Customer Impact

Less per-request allocations when using simple middleware.

See dotnet/aspnetcore#31784

@fiyazbinhasan or @smandia would one of you be able to write a sample app showing the new app.Use overload?

[fiyazbinhasan]

@Rick-Anderson sure. Will take a look at this soon 🙂
