- Prior to this change the code document provider took in many sub-providers to allow for understanding of the old RazorEditorParser AND VisualStudioRazorParser. Now that RazorEditorParser is gone we can also change the code doc provider.
- Created a new `Microsoft.VisualStudio.Editor.Razor` assembly to contain Visual Studio platform agnostic info.
- Added a new `Microsoft.VisualStudio.Editor.Razor.Test.Common` project to be the centerfold for all VisualStudio agnostic test pieces.
- Added a `Microsoft.VisualStudio.Editor.Razor.Test` project and pulled in LanguageService test files into the the Editor.Razor.Test project to correspond to their movement in the src project.
