[sparkplug/arm] Use Move32BitImmediate directly

For handles and external refs, use Move32BitImmediate directly rather
than mov -- mov will first try more compact encodings which will almost
certainly fail for embedded pointers, so it's not worth trying to use it
in baseline compilation where the compiler speed matters.
