Add codegen for ArrayType diffing (#52244)

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.
