feat(mobile): add playbackStyle to native sync API (#26541)

* feat(mobile): add playbackStyle to native sync API

Adds a `playbackStyle` field to `PlatformAsset` in the pigeon sync API so
native platforms can communicate the asset's playback style (image, video,
animated, livePhoto) to Flutter during sync.

- Add `playbackStyleValue` computed property to `PHAsset` extension (iOS)
- Populate `playbackStyle` in `toPlatformAsset()` and the full-sync path
- Update generated Dart/Kotlin/Swift files

* fix(tests): add playbackStyle to local asset test cases

* fix(tests): update playbackStyle to use integer values in local sync tests

* feat(mobile): extend playbackStyle enum to include videoLooping

* Update PHAssetExtensions.swift

* fix(playback): simplify playbackStyleValue implementation by removing iOS version check

* feat(android): implement proper playbackStyle detection

* add PlatformAssetPlaybackStyle enum

* linting
