Motivation: Changes to the typed function references and gc proposals solidified the notion of heap type, clarified nullable vs. non-nullable reference types, and introduced rtts, which contain an integer depth field in addition to a heap type. This required us to overhaul our ValueType representation, which results in extensive changes. To keep this CL "small", we do not try to implement the binary encoding as described in the proposals, but rather devise a simpler one of our own (see below). Also, we do not try to implement additional functionality for the new types. Changes: - Introduce HeapType. Move heap types from ValueType to HeapType. - Introduce Nullability for reference types. - Rework ValueType helper methods. - Introduce rtts in ValueType with an integer depth field. Include depth in the ValueType encoding. - Make the constructor of ValueType private, instead expose static functions which explicitly state what they create. - Change every switch statement on ValueType::Kind. Sometimes, we need nested switches. - Introduce temporary constants in ValueTypeCode for nullable types, use them for decoding. - In WasmGlobalObject, split 'flags' into 'raw_type' and 'is_mutable'. - Change IsSubtypeOfRef to IsSubtypeOfHeap and implement changes in subtyping. - kWasmFuncRef initializers are now non-nullable. Initializers are only required to be subtypes of the declared global type. - Change tests and fuzzers as needed.

The reference types wasm proposal dropped all subtyping. Subsequently, the 'anyref' type was renamed to externref. This changes all references of the *type* anyref to externref. Additionally, the flag that permits this extension is renamed to "reftypes" to mirror the proposal name.

Move them all into wasm-macro-gen.h, other opcodes have their macros there as well. This will make reusing these macros easier when we have other test files for SIMD. (An upcoming one is for scalar lowering tests.)

Work towards adding heap-allocated object support for wasm, according to the gc proposal. Changes: - Implement subtyping for reference types (ref s) and (optref s), where 's' is a struct type. This CL does *not* implement subtyping between struct and function types. Also, it does not handle i31refs and eqrefs. - Implement struct.set. - Change struct.get to accept an optref as argument, as required by the standard. - Allow locals to store objects of ref and optref types. - Add a test for struct.set and optref locals. Modify the test for struct.get accordingly.

The interpreter will be un-shipped soon, hence we cannot have a compilation hint for interpreted execution. This CL removes the respective enum value, removes a test which specifically tested this one option, and adapts other code to use one of the remaining hints.
