Migrate from CocoaPods to Swift Package Manager

[linear-code]

With CocoaPods reaching end of life, we will transition our React Native SDK to use Swift Package Manager.

React Native 0.75 introduced an option to integrate SPM packages into React Native applications through the spm_dependency helper that allows libraries to consume SPM packages alongside CocoaPods.

Also, React Native is actively moving toward SPM (still WIP).
