Added `TagHelper` support for `enum`s. 

- If a `TagHelper` attribute is an `enum` then you no longer need to provide the `enum` name. To override this functionality you can add the `@` symbol.
- Added code generation tests.
- Added `TagHelperDescriptorFactoryTest`s that double for Precompilation tests.
