Android: Setting numberOfLines to 0 behaves differently than on iOS.


For the `Text` component, if `numberOfLines` is set to `0`, the behavior on iOS is such that there is no limit.

On Android, the behavior is such that `numberOfLines={0}` will not render the `Text` component.

Since we want behavior to be the same across platforms, this change will make sure Android behaves the same as iOS.

**Test Plan**

Create a `Text` component specifying `numberOfLines={0}` on an Android project.

- `Text` component displays, with no limit to number of lines.

- `Text` component does not appear at all.
Closes #9188
