Migrate MediaPlayer to ExoPlayer

[VelikovPetar]

🎯 Goal

The current implementation of the AudioPlayer is based on android.media.MediaPlayer. While this was working well in most cases, we had occurrences where a voice recoding could not be played (to be more specific: mime-type = "audio/mp4;codecs=opus"). By migrating to ExoPlayer we are able to play such files (+ potentially to support a wider range of codecs)

🛠 Implementation details

• Adds exoplayer dependency to stream-chat-android-client
• Replaces the usages of the MediaPlayer with ExoPlayer (inside the NativeMediaPlayerImpl wrapper)

🎨 UI Changes

NA

🧪 Testing

Test ALL features related to voice recording:

1. Recording a new voice message (XML and Compose)
2. Listen (with skipping, pausing and resuming) the recording before sending it to the channel
3. Listen to already sent voice messages (with skipping, pausing and resuming) - both own and others
4. Switch between playing different voice messages
5. Send voice messages from iOS/React, and verify that they are playable on Android too
