Title: Created a Raw handler for templates.

This addresses the issue brought up in #2394.

I built this based on [@josevalim's suggestion](https://github.com/rails/rails/issues/2394#issuecomment-1920786), which involves creating a raw template and adding a deprecation message for default template handlers.

One issue with this as it stands is that the tests now throw some warnings; I should probably fix those up, but I wanted to get feedback on my test and this code first. I'm 99% sure that it's all good, but I've never dived into this part of Rails before.
