4806fb1c - [ParsedRawSyntaxNode] Explicitely specify if a ParsedRawSyntaxNode is null using a DataKind

[ParsedRawSyntaxNode] Explicitely specify if a ParsedRawSyntaxNode is null using a DataKind Avoid implicitely assuming 'null' node if its OpaqueSyntaxNode is null, there should be no interpretation of OpaqueSyntaxNode values, a SyntaxParseActions implementation should be able to return null pointers as OpaqueSyntaxNode.
