This change adds support for accepting a namespace name in extensible
directives. This will be needed for the @namespace directive.
Implemented new parsing and codegen for namespaces using nameof().
Also fixed any issue where we were not global::-qualifying object where it
was used in the design time code for tokens.
- Prior to this change default imports would get line pragmas generated for them because thye'd have a source location but no file path (they were a dynamic document).
- Re-generated C# files to reflect new line pragma changes.
#1110
- The lazy addition of namespaces gives the main document lowering phase an opportunity to add source location information which we then add after the main lowering.
- Re-generated csharp to capture addition of using statements that were previously overridden by defaults/imports.
#1174
- We were generating line pragmas for using directives but not line mappings. This resulted in 0 IntelliSense when written within the Razor editor.
- Regenerated test files to reflect new line mappings.
