* Updated the tokenizer and parser to operate on SyntaxTokens directly
- The tokenizer and parser now operates directly on SyntaxTokens (Green)
- The SyntaxToken(Red) is now created when the Span is built with the correct parent and position
- All other passes that run after the parsing is complete(TagHelperRewriter etc) will operate on the Red tokens.
- There is now only one type for all SyntaxTokens. They are differentiated by their SyntaxKind.
- Added equivalence checking for tokens
- Updated test code to react
- Regenerated baselines
- Migrated the completion item source provider and the legacy directive completion provider to use the new service.
- Cleaned up duplicate tests that were both verifying common completion functionality.
- Ensured that the legacy `RazorDirectiveCompletionProvider` did not result in additional Razor assembly loads when in C# scenarios.
