M135: Avoid sharing resources dict entries in CPDF_PageContentGenerator

Just as CPDF_PageContentGenerator avoids sharing a resources dictionary
between pages, the entries inside the resources dictionary should not be
shared either. Check the keys in the references dictionary that
CPDF_PageContentGenerator cares about and clone the values if those
objects are shared references.
