Remove more uses of AST to_str() and type_name()

These methods are going to be removed as they provide little benefit over the WGSL form, are a maintainance burden and they massively bloat our codebase.

This change introduces sem::CallTargetSignature, which can be used as a std::unordered_map key.
This is used in writer/spirv to replace a map that was keyed off ast::Function::type_name().
