Original change's description:
> [wasm] Refactor initializer expression handling
>
> Design doc: https://bit.ly/3xPxWUe
>
> This CL introduces two main changes:
> - Initializer expressions are now decoded by WasmFullDecoder. With
>   wasm-gc, initializer expressions are no longer just constants, and
>   require complex decoding (including stack tracking). This resulted in
>   extensive code duplication.
> - Initializer expressions are not stored explicitly by module-decoder as
>   an AST (WasmInitExpr), but rather as a WireBytesRef, and are decoded
>   again during module instantiation. This should reduce memory
>   consumption for globals and other module elements with initializer
>   expressions (which has been observed in the 40MB range in some
>   real-world benchmarks.
>
> Summary of changes:
> - Add a static parameter {kFunctionBody, kInitExpression} to the
>   WasmDecoder. Use it to specialize validation to function bodies/init.
>   expressions.
> - Introduce a new Interface for the WasmFullDecoder for init.
>   expressions.
> - Differentiate between constant and non-constant opcodes in
>   WasmFullDecoder.
> - Change representation of init. expressions in WasmModule to
>   WireBytesRef.
> - Reimplement EvaluateInitExpression in module-instantiate to re-decode
>   initializer expressions.
> - Remove some now-invalid module decoder tests.
>
> Pending changes:
> - Also refactor initializer expressions for element segment entries.
> - Reintroduce deleted tests.
