Review WasmI32AtomicWait32Descriptor::InitializePlatformSpecific

[ghost]

After atomics are implemented, this RISC-V specific code in interface-descriptors.cc needs to be reviewed:

#if !defined(V8_TARGET_ARCH_MIPS) && !defined(V8_TARGET_ARCH_MIPS64) && \
    !defined(V8_TARGET_ARCH_RISCV64)
void WasmI32AtomicWait32Descriptor::InitializePlatformSpecific(
    CallInterfaceDescriptorData* data) {
  DefaultInitializePlatformSpecific(data, kParameterCount);
}

void WasmI64AtomicWait32Descriptor::InitializePlatformSpecific(
    CallInterfaceDescriptorData* data) {
  DefaultInitializePlatformSpecific(data,
                                    kParameterCount - kStackArgumentsCount);
}
#endif
