- Revived `RazorEditorParser`.
- Made `PartialParseResult` internal and renamed it to `PartialParseResultInternal`. This fell in line with other syntax tree types.
- Moved the `RazorEditorParser` implementation away from `TextChange` and `ITextBuffer`. Instead it now relies on `SourceChange` and the VS contract `ITextSnapshot`.
- Added `RazorEditorParserTest` to ensure the changes in implementation did not impact previous functionality.
- Removed some obvious tests that unnecessarily re-tested behavior that was already verified.
- Updated tests.
- Moved several Language.Test types to the common test project so they could be reused.
#1259
Created internal + public versions of
- BlockKind
- SpanKind
- AcceptedCharacters
That way these types are only exposed through the VS apis and not
through the runtime API surface.
Also deleted RazorEditorParser. Yep. It's going to take significant work
to just port it to the language services assembly. Let's reevaluate this
when we get closer to the next foundational update.
