Lambda parameters in a @Composable that are referenced directly inside of restarting effects can cause issues or unpredictable behavior.
If restarting the effect is ok, you can add the reference to this parameter as a key in that effect, so when the parameter changes, a new effect is created.
However, if the effect is not to be restarted, you will need to use `rememberUpdatedState` on the parameter and use its result in the effect.
See https://mrmans0n.github.io/compose-rules/rules/#be-mindful-of-the-arguments-you-use-inside-of-a-restarting-effect for more information. [LambdaParameterInRestartableEffect]

## 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.
