## Content
This PR consists of several macro-blocks separated by path/package:
- `messages.impl.mediaplayer` : Global (room-wide) media player, now used only for voice messages but could be used for all media within EX in the future. It is backed by media3's exoplayer. Currently not unit-tested because mocking exoplayer is not trivial.
- `messages.impl.voicemessages.play` : Business logic of a timeline voice message. This is all the logic that manages the voice message bubble.
- `messages.impl.timeline.model` & `messages.impl.timeline.factories`: Timeline code that takes care of creating the `content` object for voice messages.
- `messages.impl.timeline.components` : The actual View composable that shows the UI inside a voice message bubble.
All the rest is just small related changes that must be done here and there in existing code.
From a high level perspective this is how it works:
- Voice messages are unlike other message bubbles because they carry state (i.e. playing, downloading...) so they have a Presenter managing this state.
- Media content (i.e. the ogg file) of a voice message is downloaded from the rust SDK on first play then stored in a voice messages cache (see the `VoiceMessageCache` class, it is just a subdirectory in the app's cacheDir which is indexed by the matrix content uri). All further play attempts are done from the cache without hitting the rust SDK anymore.
- Playback of the ogg file is handled with the `VoiceMessagePlayer` class which is basically a "view" of the global `MediaPlayer` that allow the voice message to only see the media player state belonging to its media content.
- Drawing of the waveform is done with an OSS library wrapped in the `WaveformProgressIndicator` composable.
Known issues:
- The waveform has no position slider.
- The waveform (and together with it the whole message bubble) is taller than the actual Figma design.
- Swipe to reply for voice messages is disabled to avoid conflict with the audio scrubbing gesture (to reply to a voice message you have to use the long press menu).
- The loading indicator is always shown (there is no delay).
- Voice messages don't stop playing when redacted.

* Integrate Element Call with widget API.
- Add `appconfig` module and extract constants that can be overridden in forks there.
- Add an Element Call feature flag, disabled by default.
- Refactor the whole `ElementCallActivity`, move most logic out of it.
- Integrate with the Rust Widget Driver API (note the Rust SDK version used in this PR lacks some needed changes to make the calls actually work).
- Handle calls differently based on `CallType`.
- Add UI to create/join a call.

DI infrastructure to allow injection of presenters into the timeline.
Add an `@AssistedFactory` of type `TimelineItemPresenterFactory` to a `Presenter` class and bind this factory into the TimelineItemPresenterFactory map multi binding using:
```
@Binds@IntoMap
@TimelineItemEventContentKey(MyTimelineItemContent::class)
```
A map multibinding of such factories will be available in the `LocalTimelineItemPresenterFactories` composition local for further use down the UI tree.
`TimelineItemAudioContent`:
- Use `java.time.Duration` instead of milliseconds. This will ease up things in the future because currently milliseconds are sent over the wire but in the future seconds will be sent (as per the stable MSC). Using `Duration` will allow our downstream code to be independent of what's passed over the wire.
- Rename `audioSource` property to `mediaSource` to better match its type.
`AudioMessageType`:
- Add and populate new fields `details` and `isVoiceMessage` to be used by voice messages.
- Add full screen mode for the rich text editor (RTE). When text formatting options are enabled, the editor can be dragged to full screen.
- Remove `ConstraintLayout` from `textcomposer` module, now made much simpler now the RTE supports being called in multiple layouts matrix-org/matrix-rich-text-editor#822
- Part of vector-im/element-meta#1973
- Includes design from #1315
- Fixes#1293 (through new layout)
- Fixes#1394 (through inclusion of matrix-org/matrix-rich-text-editor#824)
- Fixes#1259 (through inclusion of matrix-org/matrix-rich-text-editor#820)
