Allow `TagHelper`s inside of text/html typed script tags. 

- To limit the impact of the change ensured that we only do extra work in the case that we detect a script tag with a `type` attribute.
- The parsing changes include normal HTML parsing behaviors when we detect that a script tag has a `type` attribute with value `text/html`.
- Added unit and code generation tests to validate `text/html` script tag behavior.
