Allows [VoiceMessagePresenter] instances to keep their progress and download states while going in and out of the timeline viewport.
This is implemented by caching each instance of a TimelineItem presenter inside the RoomScope. TimelineItem presenters can move some of their state outside of the `present()` function so that such state will survive scrollings of the timeline.
Changes recording button behaviour so that
- tapping the record button starts a recording and displays the stop button
- tapping the stop button stops the recording
- tapping the delete button cancels the recording
- 'hold to record' tooltip is removed

## Content
`RustMediaLoader` creates the "${cacheDir}/temp/media" dir only once at class creation. Unfortunately when clearing an app's cache this directory will be deleted and the app's process won't be killed, so subsequent usages of the same instance of `RustMediaLoader` will not work because `cacheDirectory` does not exists. This fix makes sure that such directory is always checked and created if needed.
## Motivation and context
Fixes https://github.com/vector-im/element-x-android/issues/1788
## Screenshots / GIFs
<!--
We have screenshot tests in the project, so attaching screenshots to a PR is not mandatory, as far as there
is a Composable Preview covering the changes. In this case, the change will appear in the file diff.
Note that all the UI composables should be covered by a Composable Preview.
Providing a video of the change is still very useful for the reviewer and for the history of the project.
You can use a table like this to show screenshots comparison.

Change to `MediaPlayer` API to allow waiting for the player to be in a ready state.
This is needed in order to perform some tasks (e.g. read the media duration, seek) after changing the media file.
