Subject: [PATCH] Fix: set underlineColorAndroid properly

Summary:
This PR fixes #6332

The issue is that Android Framework will return the same drawable instance for all requests if they request for the same resource. So the changes on the drawable instance will affect all users(`TextInput` in this case). The solution is very easy, call `mutate()` before change it will get a new drawable instance which make sure the change doesn't affect other users.
Closes https://github.com/facebook/react-native/pull/12493
