This commit changes how variadic templates are represented in the demangler, in order to fix some longstanding bugs. Now instead of expanding variadic templates during parsing, the expansion is done during printing by reusing the unexpanded AST. This allows the demangler to handle cases where multiple packs contribute to a single production, and correctly handle "Dp" and "sp" productions, which corrispond to pack expansions in type and expression contexts.
