Android/ColorProps: ColorProps with value null should be defaultColor instead of transparent (#29830)

Summary:
This pr:
- Fixes: #30183
- Fixes: #30056
- Fixes: #29950
- Fixes: #29717
- Fixes: #29495
- Fixes: #29412
- Fixes: #29378

Because most of ReactProps(name = ViewProps.COLOR) accept @ Nullable Integer.
For example:
https://github.com/facebook/react-native/blob/abb6433f506851430dffb66f0dd34c1e70a223fe/ReactAndroid/src/main/java/com/facebook/react/views/text/ReactBaseTextShadowNode.java#L472-L479

After update to react-native 0.63.2 to make PlatformColor work, there is a new ColorPropSetter.
https://github.com/facebook/react-native/blob/abb6433f506851430dffb66f0dd34c1e70a223fe/ReactAndroid/src/main/java/com/facebook/react/uimanager/ViewManagersPropertyCache.java#L194-L215

But ColorPropSetter won't return an nullable value with getValueOrDefault, it will always return it's defaultValue which is 0.
And 0 is equal to TRANSPARENT, will cause <Text /> disappear.
## Changelog

[Android] [Fixed] - ColorProps with value null should be defaultColor instead of transparent

Pull Request resolved: #29830

Test Plan:
Please initiated a new project and replaced the app with the following code:
```
import * as React from 'react';
import {Text, View, TouchableOpacity, PlatformColor} from 'react-native';

export default function App() {
  const [active, setActive] = React.useState(false);

  return (
    <View>
      <Text style={active ? {color: 'green'} : null}>Example</Text>
      <Text
        style={
          active ? {color: PlatformColor('android:color/holo_purple')} : null
        }>
        Example2
      </Text>
      <TouchableOpacity onPress={() => setActive(!active)}>
        <Text>Toggle Active</Text>
      </TouchableOpacity>
    </View>
  );
}
```

Thanks you so much for your code review!
