Summary [Wasm-GC] Implement casts at Wasm-JS function call boundaries

When calling into Wasm from JS, `ToWebAssemblyValue` needs to be called on JS values to convert them to Wasm values. For GC types, this is currently not implemented. In general, it's necessary to add a `extern.internalize` and `ref.cast` to the target Wasm type on such a call. In the other direction, `ToJSValue` is typically a no-op for Wasm GC values, but it still needs to be enabled. The machinery to do these casts is already in JSC, but it needs to be hooked up to code in JSToWasm.cpp and WasmToJS.cpp to do the right thing.
