[ios] implement TrackRecording place page

1. add an new screen (layout)
2. add TR icon for the bottom tabbar
3. share current location from the TR PP
4. refactor TR manager to properly handle state updates and pass them to the LiveActivityManager and PlacePage
5. add init/update with TrackInfo/EleInfo methods to the PlacePageData and PlacePagePreviewData to update the PP state
