feat: ios - add share extension custom view (react)

[achorein]

Summary

This feature seems long awaited, along with the famous “custom view”. I haven't developed it yet, as it implies a different behavior between iOS and Android, and therefore the implementation of two codes on your application. On my side, this requires a lot of work, with a change of architecture for the iOS part.

But I think I can now start working on it

First, I'm thinking of setting up a simple callback system, i.e. with a static “custom view” (non-modifiable) which, when validated, will call a async function provided in the app code.

Todo

• Add React Bridge in ShareExtension (expo 51, old architecture)
• Add React Bridge in in new architecture (expo 52)
• Load a React custom view in share menu
• Add callback to handle share action in App code
• Add configuration to enable/disable react view
• Add a custom view example
• Handle of type of content (text/weburl/image/files)
• Check backward compatibility for simple share intent
• Update README.md
