feat: add displayName to touchables (#29531)

Summary:
Since TouchableHighlight and TouchableOpacity are being exported using `forwardRef`, it's messing up jest's snapshots and some matchers.
This commit 4b935ae fixed this for components being mocked on [setup.js](https://github.com/facebook/react-native/blob/master/jest/setup.js). However, these Touchables aren't being mocked.

It resolves #27721

## Changelog

[General] [Added] - Add displayName to TouchableHighlight and TouchableOpacity

Pull Request resolved: #29531

Test Plan: Check the new snapshots.
