* Refactor Tuple Type Syntax This patch: - Refactors TypeArgumentListSyntax and TypeArgumentListSyntaxData to use the SyntaxCollection and SyntaxCollectionData APIs. - Refactors TupleTypeElementSyntax to own its trailing comma, and updates the tests accordingly. - Provides an infrastructure for promoting types to use the SyntaxCollection APIs * Addressed comments. * Renamed makeBlankTypeArgumentList() * Update makeTupleType * Changed makeTupleType to take an element list. * Updated comment. * Improved API for creating TupleTypeElementListSyntax'es * Added round-trip test * Removed last TypeArgumentList holdovers. * Fixed round-trip test invocation
