fix(style)(backgroundSize) - Passing unsupported backgroundSize on android causes crash (#55904)

Summary:
Below snippet would lead to divide by zero crash on android. Currently, "`cover` | `contain`" keywords are not supported for background size as these only work on actual images (`url()` syntax) and not on gradients. These keywords were supposed to be removed in this [commit](https://github.com/facebook/react-native/pull/52282/changes/34c041ce1e13eddbc51bd473c6d241e3ca040887) and added later in this [PR](https://github.com/facebook/react-native/pull/54994)

```jsx
<View
  style={{
    experimental_backgroundImage: "radial-gradient(circle, #f093fb, #f5576c)",
    experimental_backgroundSize: "cover",
    width: 100,
    height: 100
  }}
/>;

```
