Crash when animating Transform property using native driver downlevel

[kmelmon]

Repro Steps

Install OS build that's < 19H1 (eg RS5)
Run RNTester on this build with this change to AnimatedExample.js:

title: 'Transform Bounce',
description:
  'One `Animated.Value` is driven by a ' +
  'spring with custom constants and mapped to an ' +
  'ordered set of transforms.  Each transform has ' +
  'an interpolation to convert the value into the ' +
  'right range and units.',
render: function() {
  this.anim = this.anim || new Animated.Value(0);
  return (
    <View>
      <RNTesterButton
        onPress={() => {
          Animated.spring(this.anim, {
            toValue: 0, // Returns to the start
            velocity: 3, // Velocity makes it move
            tension: -10, // Slow
            friction: 1, // Oscillate a lot
            **useNativeDriver:true**

Go to the Animated Examples page
Hit the "Press to Fling it" button

The issue here is that when running downlevel, we don't support the ActualSize facade, which is needed for the Transform property to work, and we have code to protect against static Transform values, but something in the animation code path is still trying to run the animation. We need to add a check in the transform animation code that we're on a build that supports this stuff.

@StephenLPeters Our support level is only for 19H1 but we want silent failures as much as possible for lower versions. Let's fix the crash here and have it no op.
