Add media file limit size warning and media quality selection (#5131)

* Add `VideoCompressorPreset` enum

This represents the different compression presets used for processing videos before uploading them

* Add `VideoCompressorHelper` util class to calculate the scaled output size of the video given an input size and its optimal bitrate

Also add `MediaOptimizationConfig` which will be used to decide how to apply compression in `MediaPreProcessor`

* Add `RustMatrixClient.getMaxFileUploadSize()` function and `MaxUploadSizeProvider` so we can import only this functionality into other components

* Try preloading the max file upload size the first time we get network connectivity - it's a best effort

This should help ensure we'll have this value available later, even if we still need to load it asynchronously.

* Split the `compressMedia` preference into `compressImages` and `compressMediaPreset`

* Modify the media processing parts to use the new classes and utils

* Add `MediaOptimizationSelectorPresenter`, which will retrieve the compression values and the max file upload size, also estimating the compressed video file sizes if needed.

* Add a feature flag to allow selecting the media upload quality per upload

* Integrate the previous changes with the attachments preview screen

Add strings from localazy too.

* Adapt the rest of the app calls to upload media to using the media optimization configs

* Allow modifying the default compression values in advanced settings, based on the feature flag value

* Pass the `fileSize` in `MediaUploadInfo` too, to be able to check it against the `maxUploadSize`

* Update screenshots
