[native] introduced flow type for @expo/react-native-action-sheet

Summary:
Now that we are using @expo/react-native-action-sheet we need to introduce the following flow types to use the action sheet in our codebase. I read through the source code, and used types.ts when writing the flow types.

Linear Task: ENG-2145

Test Plan: All the testing for this diff came from its use in D5524. In that diff I was able to implement the action sheet using the flow types I created in this diff, and I received no flow errors which I believe to be a good indicator that everything is correct. I noticed in the flow docs, there was a section to write tests; however, I also noticed that the other flow-typed library definitions in our code base also don't have any tests, but if this is something we want to get done, I will take a look into it
