Generate `async` lambda for template attributes. 

- Template attributes should be of type `Func<TextWriter, Task>`. We weren't generating an `async` lambda for attributes prior to this change resulting in a compilation failure when used at runtime and the inability to `@await` code (unless a user returns some sort of `Task`).
- Updated code generation files to reflect the new code generation behavior.
