Add pdf_dict_put_dict family of functions.

pdf_dict_put_dict creates a new empty dictionary, inserts it
into the parent dictionary, and returns a borrowed reference to it.

These functions should simplify document creation by removing the
need to wrap creation with try/catch for reference counting cleanup.
