Despite `tint::ast::type::Type` being in the AST namespace, these classes are clearly not AST nodes: * They don't derive from ast::Node * They're deduplicated by the type manager * None of the types have an Source - they have no lexical declaration point * The fact we have `ast::Struct` and `ast::type::Struct` clearly demonstrates what is an AST node, and what is a type. * We have code scattered in the codebase (TypeDeterminer, writers, etc) that create new types after parsing - so clearly not part of the original syntax tree. Types in tint are closer to being semantic info, but due to the parse-time generation of types, and tight dependency of ast::Nodes to types, I'd be reluctant to class these as semantic info. Instead, put these into a separate root level `tint::type` namespace and `src/tint` directory. The fact that types exist in the ast::Module has already caused bugs (https://dawn-review.googlesource.com/c/tint/+/37261). This is a first step in separating out types from the ast::Module.
