Summary:
Some props must have their default values set by native. To be able to support this, we have to introduce a null as a supported default value for some types. In this diff I'm adding support for null default values for float props. An example of this to be useful is `ReactDrawerLayoutManager`:
```
Override
public void setDrawerWidth(ReactDrawerLayout view, Nullable Float width) {
int widthInPx =
width == null
? LayoutParams.MATCH_PARENT
: Math.round(PixelUtil.toPixelFromDIP(width));
view.setDrawerWidth(widthInPx);
}
```
We need to be able to generate an interface method, that accepts a boxed `Float` value instead of the primitive `float` so that the native code can decide what value to use by default (`LayoutParams.MATCH_PARENT` in this case).
