Fix serialization for vector of primitive type (facebook#53982)

Summary:
Pull Request resolved: facebook#53982

This diffs adds specific `toDynamic` conversions for props defined as arrays holding primitive types. This fixes the serialization of `std::vector<Float>` that was failing to correctly convert to a `folly::dynamic` type when using Props 2.0.
