Stop generating RCTThirdPartyLibraryComponentProvider (#47517)

Summary:
Pull Request resolved: #47517

The `RCTThirdPartyLibraryComponentProvider` has been introduced to automate the component registration of third party libraries in the apps. However, it has some serious flaws:

* It is generated in the React/Fabric folder, which means that it is generated in node_modules
* It is generated when the user installs the components in the app, which means that we can't prebuild and redistribute React Native as a binary
* it does not work with Frameworks and dynamic linking: in this scenarion, Fabric must build in isolation and if there are third party libraries involved, the lookup of the `xxxCls` function will fail

This change removes the generation of the `RCTThirdPartyLibraryComponentProvider`. In the next diffs we will implement a different mechanism to register components
