Roll out package info validation

Summary:
## Context
Every time we require a NativeModule in Java, we [first try to create it with the TurboModuleManager](https://fburl.com/diffusion/3nkjwea2). In the TurboModule infra, when a NativeModule is requested, [we first create it](https://fburl.com/diffusion/d2c6iout), then [if it's not a TurboModule, we discard the newly created object](https://fburl.com/diffusion/44gjlo6y). This is extremely wasteful, especially when a NativeModule is requested frequently and periodically, like UIManagerModule.

Therefore, in D24811838 (803a26c) fkgozali launched a fix to the infra that would avoid creating the non-TurboModule object in the first place. Today, we're launching this optimization.
