[av] audio: refactor interruption modes to enums, export missing type

[Simek]

Why

This PR starts the effort to prepare the Audio module for the docs autogeneration.

There will be more breaking changes to come in the future PRs, see:

• https://github.com/expo/expo/blob/main/packages/expo-av/src/Audio/RecordingConstants.ts#L3

How

The first parts refactors the interruption modes constants to the newly added InterruptionModeAndroid and InterruptionModeIOS enum types.

I have also spotted during fixes for NCL screens, that AudioMode type is not properly exported by av package, which forced users to define those object types manually. This problem also has been fixed, and for the clarity, I have moved all the Audio related types to the new Audio.types.ts file.

Test Plan

yarn and yarn lint commands ended with a success.

NCL apps build and runs on the iOS device. Audio screen are working as expected.

Checklist

• This diff will work correctly for expo build (eg: updated @expo/xdl).
• This diff will work correctly for expo prebuild & EAS Build (eg: updated a module plugin).

Hello. Could you help?

So what do I need to put now if I've got this at the moment:

interruptionModeIOS: Audio.INTERRUPTION_MODE_IOS_DO_NOT_MIX

[Simek]

Hi @lpgm, you need to use InterruptionModeIOS exported from av:

import { InterruptionModeIOS } from 'expo-av';
interruptionModeIOS: InterruptionModeIOS.DoNotMix;

Also it looks like Audio docs are not updated yet, I will look into that soon. 🙂

However, this change has been mentioned in package changelog, where the current enum names were listed:

• https://github.com/expo/expo/blob/main/packages/expo-av/CHANGELOG.md#-breaking-changes-1

Thanks a lot, @Simek . I was directed to that changelog, but I wasn't sure about the format of what was needed.
