Builds the complete code for a component based on the provided spec.
This function generates the full code representation of a component, including
the root component code and recursively pulling in dependency components and also replacing
the placeholders for those dependency components in the parent component's code with the
actual code for those dependency components (which were generated after the parent component was generated).
