Adds a loader (with shadow copying in server mode) based on the Roslyn
Analyzer loader design.
Adds some targets to the Razor SDK that we can use to compute the
configuration and extensions.
Passes all of the metadata through to the command line tools so they can
deal with extensions.
- Instead of using Razor/Mvc TemplateEngine use `RazorProjectEngine`. This involved changing several locations (each of which used `RazorTemplateEngine` in an entirely different way) to use the RazorProjectEngine's two Process methods.
- Changed an unused public API `VisualStudioRazorParser.TemplateEngine` to `VisualStudioRazorParser.RazorProjectEngine`.
- Ported the remainder of `RazorEngineBuilder`'s extension methods over to `RazorProjectEngineBuilder`. These were used in tests and our `RazorGenerate` tool.
- Added a few test helper methods/classes to enable simple testing of the `RazorProjectEngine`.
- Resolved several test hacks that were working around little discrepancies each of the `RazorTemplateEngine` APIs.
- Changed the template engine factory service to be a project engine factory service.
- Changed all existing APIs to utilize `RazorProjectFileSystem`. This was possible because `RazorProjectFileSystem` inherits from RazorProject.
- Renamed `FileSystemRazorProject` to `DefaultRazorProjectFileSystem`.
- Renamed FileSystemRazorProjectItem` to `DefaultRazorProjectItem`.
- Obsoleted `RazorProject.Create`
