Summary [JSC] Wasm GC struct members should be naturally aligned

At present, e.g. ref members can be placed anywhere within the JSWebAssemblyStruct::m_payload allocation; for concurrent JIT on 32-bit (and, AIUI, concurrent GC on 64-bit,) these need to be 8-byte aligned. Also, I suspect aligning the scalar types could be a slight performance win on ARM.
