De-genericize IGListBindingSectionController for Swift migration
Summary:
## Plan
This module doesn't need A/B testing and will be migrated directly.

## This Diff
Removes the `__covariant ObjectType : id<IGListDiffable>` lightweight generic type parameter from `IGListBindingSectionController`. Swift generic types cannot be exposed to ObjC, so any generic ObjC class must lose its type parameter when converted to Swift. This degenerification is a required prerequisite for future Swift migration.

Changes:
- Removed the generic type parameter from the class header, replacing `ObjectType` with `id<IGListDiffable>` in the `object` property declaration
- Removed the generic specialization from the `IGContentAppreciationGiftSectionController` subclass header
- Simplified 87 Swift files that referenced `ListBindingSectionController<ListDiffable>` or `ListBindingSectionController<any ListDiffable>` or other specializations to plain `ListBindingSectionController`
- Added ObjC casts at 3 callsites where the `.object` property was used with specialized type access (`IGAudioSearchResultsViewController.mm`, `IGDSShowcaseListExampleModel.m`)
- Added Swift casts at callsites in `BCNComposerPostSectionController`, `BCNComposerViewController`, `BCNPostingStatusDatasource`, `BCNComposerAssetSectionController`, and `GiftsFeedSectionController` where `.object` was accessed as the previously-specialized type
