Support setting hitSlop with single value

Summary:
The native side supports this in https://github.com/facebook/react-native/blob/main/ReactCommon/react/renderer/graphics/conversions.h#L156 but it fails on the Java side.

Changelog: [Android][Fixed] Enable hitSlop to be set using a single number.
