Rename Codegen Component Descriptors Entrypoint for FAC and hook it up in DefaultComponentsRegistry

Summary:
As part of [FAC](https://docs.google.com/document/d/1WACeVolFTrsJqbsUpHwYKPVw0EijdG6ZyFPYprSg8QQ/edit?usp=sharing) rollout, we are hooking the code-generated ComponentDescriptors.cpp (the Codegen list of components) via [registerComponentDescriptorsFromEntryPoint](https://www.internalfb.com/code/fbsource/[a60437056a3b58f0bcc9fded7b851cbf09f377c7]/xplat/js/react-native-github/packages/react-native-codegen/DEFS.bzl?lines=147) however in Bridgeless mode this is the same hooking mechanism used by AMA, Twilight, Anna & Ariane to link their individual app registries :

 **AMA** :

**Twilight** : 

https://www.internalfb.com/code/fbsource/[e2855199ad37704c474957162d24efe666de4304]/fbandroid/java/com/oculus/twilight/crossapp/reactpackage/fabric/components/jni/OnLoad.cpp?lines=13-14

**Anna** : 

https://www.internalfb.com/code/fbsource/[e2855199ad37704c474957162d24efe666de4304]/fbandroid/java/com/facebook/anna/app/cpp/OnLoad.cpp?lines=13-14


**Ariane** :
https://www.internalfb.com/code/fbsource/[e2855199ad37704c474957162d24efe666de4304]/fbandroid/java/com/facebook/rlr/ariane/crossapp/components/OnLoad.cpp?lines=13-14

Hence for the codegen hooking up renaming the function to `registerCodegenComponentDescriptorsFromEntryPoint` and thus correspondingly changing DefaultComponentsRegistry.h & .cpp
