/* To call this function, the heap_ref must still not be initialized. Also, the heap must be
   one of the "basic" ones - created with pas_heap_config_utils or something that broadly uses
   the same defaults. In particular, it must be the kind of heap that expects the runtime_config
   to be a pas_basic_heap_runtime_config. This will copy the runtime_config you pass and combine
   it with the basic_heap_page_caches to create a new pas_basic_heap_runtime_config. */
