Support font-variant-ligatures values (#36740)

Summary:
The text style prop `fontVariant` in React Native is supposed to map to the CSS `font-variant` property. The CSS property is a short-hand for the following CSS properties:

- [font-variant-alternates](https://developer.mozilla.org/en-US/docs/Web/CSS/font-variant-alternates)
- [font-variant-caps](https://developer.mozilla.org/en-US/docs/Web/CSS/font-variant-caps)
- [font-variant-east-asian](https://developer.mozilla.org/en-US/docs/Web/CSS/font-variant-east-asian)
- [font-variant-emoji](https://developer.mozilla.org/en-US/docs/Web/CSS/font-variant-emoji)
- [font-variant-ligatures](https://developer.mozilla.org/en-US/docs/Web/CSS/font-variant-ligatures) 👈
- [font-variant-numeric](https://developer.mozilla.org/en-US/docs/Web/CSS/font-variant-numeric)
- [font-variant-position](https://developer.mozilla.org/en-US/docs/Web/CSS/font-variant-position)

Currently React Native only supports a subset of the values from `font-variant-numeric` and `font-variant-caps`.

This change increases the `font-variant` support by adding all values from `font-variant-ligatures`.

## Changelog:

[iOS] [Added] - Add all fontVariant values for font-variant-ligatures
[Android] [Added] - Add all fontVariant values for font-variant-ligatures
