Remove all sem::Type references from the AST. ConstructedTypes are now all AST types. The parsers will still create semantic types, but these are now disjoint and ignored. The parsers will be updated with future changes to stop creating these semantic types. Resolver creates semantic types from the AST types. Most downstream logic continues to use the semantic types, however transforms will now need to rebuild AST type information instead of reassigning semantic information, as semantic nodes are fully rebuilt by the Resolver.
