Our Codegenerated components are not generating code for `getDebugProps`. This change modifies Codegen to add those functions for all the codegen components.
## Changelog:
[General][Added] - Added getDebugProps to codegen
## Facebook:
`getDebugProps` are required by Fantom to write tests. However, we can't generate these function for third party components, because codegen can generate arbitrary structs and we don't have a generic `toString()` method that can be used or automatically generated by C++.
By generating this function only for Core Components, we can ensure that we can write Fantom tests without breaking all the users of React Native.

Summary:
`react-native/codegen` uses `babel/parser` and `babel/core` but does not declare dependency on them. Depending on how packages are hoisted (and especially in pnpm setups), this causes crashes during codegen.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52244
The ArrayType props converts to std::vector. This prompted the need for `toDynamic(const T&)` conversion functions as this breaks to potential reliance on all type instances having a `toDynamic()` function available. This includes:
- array of arrays types
- array of objects types
- object with arrays
The ArrayType conversion uses the availability of the `toDynamic` conversion methods for all supported types to convert the values stored by the `std::vector` to `folly::dynamic` values to be stored on a `folly::dynamic::array`.
The diff removes unnecessary conversion methods implemented previously for the core components prop diffing. These are now handled by the generic `toDynamic(const std::vector<T>&)` conversion method.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52243
Building on the availability of `toDynamic` conversion methods for all supported property types, this diff adds support for diffing of `ObjectType` props.
The template adds the generation of a default comparator for the generated C++ struct. The struct also gains a `toDynamic` conversion method that will convert each property of the object type to a `folly::dynamic` value.
Primitive types make use of the implicit conversion supported by `folly::dynamic`, all other types are converted using `toDynamic`.
The `toDynamic` logic is implemented as a method defined on the struct to avoid increased binary size when required multiple times by the prop diffing implementation.
The external `toDynamic` conversion function calls the struct method directly. This enables support for converting object types using object types within their props.

Add support for converting string and int32 enum types to `folly::dynamic` and generating the correct property diffing for it conditionally adding the prop value to the prop diff result.
This diff updates the template to convert the enum back to the original string representation provided from the JS side based on the current generated C++ enum value.
The string enum re-uses the existing `toString` conversion. The number enum generates the switch-case mapping required to map back the C++ enum value to the original value assigned to it.
