Deprecate LazyReactPackage.getReactModuleInfoProviderViaReflection

Summary:
There are two different ways of getting the ReactModuleInfoProvider from LazyReactPackage:
1. static LazyReactPackage.getReactModuleInfoProviderViaReflection(LazyReactPackage)
2. LazyReactPackage.getReactModuleInfoProvider()

The first way calls into codegen that only works within Meta's infra. This code-path is *now* dead. Therefore, this diff deprecates the first path, to make LazyReactPackage less confusing.

This diff simplifies the implementation to return an empty ReactModuleInfoProvider for the v0.72 cut.

In the v0.73 cut, we'll just outright delete this method.
