Let lib maintainer be explicit with componentProvider mapping (#47520)
Browse files Browse the repository at this point in the history 
Summary:

Right now, when a 3p library needs to register a component in the component system, we have to crawl the library to try and get the mappng, best effort.

With this approach, we are enriching the `codegenConfig` property to allow library developers to define the mapping themselves.

For example:
```json
//...
"codegenConfig": {
    //..
    "ios": {
      "componentProvider": {
        "RNTMyNativeView": "RNTMyNativeViewComponentView"
      }
    }
  },
```
means that the JS component `RNTMyNativeView` will be mapped to the `RNTMyNativeViewComponentView` class.

This also work for local apps, and it warns the users about what libraries are using the deprecated approach, so they can open an issue or a PR to those libraries.

## Changelog:
[iOS][Added] - Allow 3p developers to specify the association between components and classes in Fabric
