[Mobile] Use react-native-url-polyfill in globals (#27867)

* Use react-native-url-polyfill in globals

* Ensure we are using react-native-url-polyfill in native url tests

* Re-enable isURL fixture tests for mobile

* Update exclusions for lack of unicode support

* Remove native variant of is-url

This platform fork is no longer necessary, since we are using the
polyfill globally.
